delivered the opinion of the Court.
On September 17,1930, respondent borrowed from petitioner the • sum of $300, and as security for its payment executed an assignment of a portion of his wages thereafter to be earned. On March 3, 1931, respondent filed a voluntary petition in bankruptcy in a federal district court in Illinois, including in his schedule of liabilities the foregoing loan, which constituted a provable claim against the estate. Respondent was adjudicated a bankrupt; and, on October 10, 1932, an order was entered discharging him from all provable debts and claims. On October 18, . 1932, petitioner brought an action in the municipal court of Chicago against respondent’s employer to enforce the assignment in respect of wages earned after the adjudication. Thereupon, respondent commenced this proceeding in the court which had adjudicated his bankruptcy and ordered his discharge, praying that petitioner be enjoined from further prosecuting said action or attempting to enforce its claim therein made against respondent under the wage assignment. The bankruptcy court, upon consideration, entered a decree in accordance with the prayer ; and this decree on appeal was affirmed by the court below, 67 F. (2) 998, following its decision in In re Skorcz, 67 F. (2d) 187.
Challenging this decree, petitioner contends: That the bankruptcy court was without jurisdiction to entertain *239 a proceeding to enjoin the prosecution of the action in the municipal court; that, assuming such jurisdiction, the rule is that an assignment of future wages constitutes an enforceable lien; but that, in any event, the highest court of the State of Illinois has so decided, and by that decision this court is bound.
First.
The pleading by which respondent invoked the jurisdiction of the bankruptcy court in the present case is in substance and effect a supplemental and ancillary bill in equity, in aid of and to effectuate the adjudication and order made by the same court. Tjhat a federal court of equity has jurisdiction of a bill ancillary to an original case or proceeding in the same court, whether at law or in equity, to secure or preserve the fruits and advantages of a judgment or decree rendered therein, is well settled.

These principles apply to proceedings in bankruptcy.
In re Swofford Bros. Dry Goods Co.,
What has now been said establishes the authority of the bankruptcy court to entertain the present proceeding, determine the effect of the adjudication and order, and enjoin petitioner from its threatened interference therewith. It does not follow, however, that the court was bound to exercise its authority. And it probably would not and should not have done so except under unusual circumstances such as here exist. So far as appears, the municipal court was competent to deal with the case. It is true that respondent was not a party to that litigation; but undoubtedly it was open to him to intervene and submit to that court the question as to the effect upon the subject matter of the .action of the bankruptcy decrees. And it may be conceded that the municipal court was authorized in the law action to afford relief the equivalent of that which respondent now seeks in equity. Nevertheless, other considerations aside, it is clear that the legal remedy thus afforded would be inadequate to meet the requirements of justice. As will be shown in a moment, the sole question at issue is one which the highest court of the State of Illinois had already resolved against respondent’s contention. The alternative of invoking the equitable jurisdiction of the bankruptcy court was for respondent to pursue an obviously long and expensive course of litigation, beginning with an intervention in a municipal court and followed by successive appeals through the state intermediate and ultimate courts of appeal, before reaching a court whose judgment upon the merits of the question had not been predetermined. The *242 amount in suit is small, and, as pointed out by Judge Parker in Seaboard Small Loan Corp. v. Ottinger, supra, at p. 859, such a remedy is entirely inadequate because of the wholly disproportionate trouble, embarrassment, expense, and possible loss of employment which it involves.
Second.
Whether an assignment of future earned wages constitutes a lien within the meaning of § 67 (d) of the bankruptcy act,

is a matter upon which the decisions of the state and federal courts are not in complete accord; although by far the larger number of cases and the greater weight of authority are in the negative. We do not stop to review the state decisions. Among those which deny the existence of the lien are
Leitch
v.
Northern Pacific Ry. Co.,
“ The discharge in bankruptcy operated to discharge these obligations as of the date of the adjudication, so that the obligations were discharged before the wages intended *243 as security were in existence. The law does not continue an obligation in order that there may be a lien, but only does so because there is one. The effect of the discharge upon the prospective liens was the same as though the debts had been paid before the assigned wages were earned. The wages earned after the adjudication became the property of the bankrupt clear of the claims of all creditors.”
This conclusion finds ample support in the following decisions among others.
In re Home Discount Co.,
The earning power of an individual is the. power to create property; but it is not translated into property within the meaning of the bankruptcy act until it has brought earnings into existence. An adjudication of bankruptcy, followed by a discharge, releases a debtor from all previously incurred debts, with certain exceptions not pertinent here; and it logically cannot be supposed that the act nevertheless intended to keep such debts alive for the purpose of permitting the creation of an enforceable lien upon a subject not existent when the bankruptcy became effective or even arising from, or connected with, preexisting property, but brought into being solely as the fruit of the subsequent labor of the bankrupt.
Third.
To the foregoing array of authority petitioner opposes the decisions of the Supreme Court of Illinois in
Mallin
v.
Wenham,
We find it unnecessary to consider whether this contention would in a different case find support in § 34 of the Judiciary Act of 1789, now § 725, Title 28, U.S.C., 3 since we are of opinion that it is precluded here by the clear and unmistakable policy of the bankruptcy act. It is important to bear in mind that the present case is one not within the jurisdiction of a state court, but is a dependent suit brought to vindicate decrees of a federal court of bankruptcy entered in the exercise of a jurisdiction essentially federal and exclusive in character. And it is that situation to which we address ourselves, and to which our decision is confined.
One of the primary purposes of the bankruptcy act is to
“
relieve the honest debtor from the weight of oppressive indebtedness and permit him to start afresh free from the obligations and responsibilities consequent upon busir ness misfortunes.”
Williams
v.
U.S. Fidelity & G. Co.,
When a person assigns future wages, he, in effect, pledges his future earning power. The power of the individual to earn a living for himself and those dependent upon him is in the nature of a personal liberty quite as much as, if not more than, it is a property right. To preserve its free exercise is of the utmost importance, not only because it is a fundamental private necessity, but because it is a matter of great public concern. From the viewpoint of the wage earner there is little difference between not earning at all and earning wholly for a creditor. Pauperism may be the necessary result of either. The amount of the indebtedness, or the proportion of wages assigned, may here be small, but the principle, once established, will equally apply where both are very great. The new opportunity in life and the clear field for future effort, which it is the purpose of the bankruptcy act to afford the emancipated debtor, would be of little value to the wage earner if he were obliged to face the necessity of devoting the whole or a considerable portion of his earnings for an indefinite time in the future to the payment of indebtedness incurred prior to his bankruptcy. Confining our determination to the case in hand, and leaving prospective liens upon other forms of acquisitions to be dealt with as they may arise, we reject the Illinois decisions as to the effect of an assignment of wages earned after bankruptcy as being destructive of the purpose and spirit of the bankruptcy act.
Decree affirmed.
