The district court’s computation of the damages due a disabled seaman is attacked on the basis that the court erred in the method it used to discount the award to present value, in failing to make allowance for income and social security taxes that would not be paid if the seaman did not work, and in allowing damages for loss of society to a minor son. We find that the issue concerning the award to the minor son was timely raised and, reaching the merits, that federal law permits no such *477 award. We also find merit to the other attacks on computation of damages and remand for their redetermination.
Richard E. Madore, a Jones Act seaman, was totally disabled as a result of his employer’s fault. At the time of trial, he was thirty-four- years old. There was evidence that he then had a life expectancy of 39.1 years, and a work-life expectancy of 30.8 years. Without further explanation, the district court computed his damages as follows:
“for after tax loss of earnings” from the date of injury to March 1,1983 (a month before trial) 71,359
“for after tax loss of future earnings reduced to its present cash value based upon an annual discount rate of 6.56%” 1,458,898
“for past pain, suffering, discomfort, inconvenience and disfigurement up until March 1,1983.” 150,000
“for future pain, suffering, discomfort, inconvenience and disfigurement.” 350,000
In addition, the court awarded $50,000 to Madore’s wife for loss of consortium and society and $25,000 to Madore’s minor son “for the loss of society of his father.”
The defendant has satisfied the judgment in full save for the items contested in this appeal.

Jones & Laughlin Steel Corp. v. Pfeifer,
— U.S. -,
II.
In computing the damages to be awarded for loss of future earnings, the district court said only what has already been quoted. Using a discount rate of 6.56%, it is possible, however, to determine how the dollar sum was calculated by reviewing the record. The district court appears to have relied on the testimony of an expert witness called by Madore, James Mandel, a certified public accountant. Mandel estimated that the stream of future earnings lost by Madore, computed after the payment of income tax, amounted to $1,611,-257. The district court appears to have deducted earnings lost from the date of Madore’s injury to March 1, 1983, because this amount, $71,359, was allowed separately. Mandel also assumed that Madore’s *478 actual future earnings would have increased $81,000 after he had received post-injury rehabilitation training. Deduction of this would result in the gross figure used by the district court, $1,458,898.
The discount rate applied, 6.56%, was based on a twenty-one year average of rates paid on United States Treasury bills, not on market rates available at the time of judgment as required by Culver 1 2 The district court computed the likelihood and amount of Madore’s future income growth by taking history as a guide. 3 It is superficially consistent to determine interest rates in the same fashion. However, the loss of wages is not based on the wage-earner’s average earnings but on his earnings at the time of injury, the moment at which he suffers damage. If judgment is rendered for the wage-earner, the damage award is paid at a single moment, after judgment is rendered. It can then be invested, at that moment. The market rate then available, not the average rate that would have been paid had the money been invested in the past, determines what the award will yield. The only current or market discount rate supported by the record was 10.25%, the rate testified to by Mandel. This was the rate, adjusted for tax effects, that should have been used.
III.
Both Mandel and the defendant’s expert, Dr. Kenneth Boudreaux, testified that Madore had a worklife expectancy of 25.8 years, basing their opinions on the worklife expectancy rates compiled by the United States Department of Labor. No evidence was adduced to show that Madore’s personal characteristics were likely to give him a longer worklife. Yet the district court based the award on a worklife expectancy of 30.8 years, presumably because Madore would reach age 65 at that time.
This was erroneous. Even if retirement age for Madore could be anticipated to be age 65, it is far from certain that, even in the absence of this injury, he would have continued to work until that time. He might have, as some workers do, decided to retire early. He might have become disabled before then as a result of illness or some other misadventure. He might have died before then. The phrase “work-life expectancy” literally reflects its meaning: the average number of years that a person of a certain age will both live
and
work. Such an average is not conclusive. It may be shown by evidence that a particular person, by virtue of his health or occupation or other factors, is likely to live
and
work a longer, or shorter, period than the average. Absent such evidence, however, computations should be based on the statistical average.

IV.
In computing the loss of future earnings, gross earnings should not be
*479
used. Unless the amounts the worker would have been required to pay in income taxes and social security taxes is negligible
4
or should, for some articulated reason, be disregarded, the lost income stream must be computed after deducting the income taxes and social security taxes the worker would have paid had he continued to work, for he is entitled only to be made whole for what he has lost, his net income.
Culver I,
The defendants counter that no objection was made in the district court to the failure to deduct taxes. The objection was sufficiently made by cross-examining Mandel concerning his failure to make such an allowance. In addition, the defendant’s expert witness reférred, on cross-examination, to the fact that he had included social security taxes in his own calculations.

The spouse of an injured crew member who survives his injury may recover her loss of society in an action for unseaworthiness because such an action is based on general maritime law.
Beltia v. Sidney Torres Marine Transport, Inc.,
Neither the Jones Act in terms nor any case cited to us permits recovery by a child for loss of the society of a living parent. An overwhelming majority of the courts that have considered such a claim under state tort law have rejected it, for various reasons.

See
Annot.,
Madore contends that Ingram waived its right to object to this claim by failing to move to dismiss it before or during trial on the merits. A defense that the complaint fails to state a claim for which
*480
relief can be granted may not be asserted for the first time on appeal.
See, e.g., Brule v. Southworth,
Before judgment Ingram did file a memorandum in the district court denying that recovery might be had for such a claim. This pre-judgment argument sufficed. 8
For these reasons the judgment is REVERSED and the case is REMANDED for further proceedings consistent with this opinion.
Notes
.
Pfeifer
involved a claim by a longshoreman for negligence under § 5 of the Longshoremen’s and Harbor Workers’ Compensation Act, 33 U.S.C. § 905 (1976). This case arises under the Jones Act, 46 U.S.C. § 688 (1976). Because the parties concede that
Pfeifer
is inapplicable because it was decided after judgment was rendered, we do not comment either on whether the same principles are applicable to computations under those two statutes or on retroactivity of
Pfeifer. Cf. Solem v. Stumes,

See
. The district court calculated Madore’s future lost earnings by applying a seven percent growth rate to his present earnings. According to government statistics introduced into evi- . dence by Madore, this was the rate of income growth experienced by transportation workers from 1964 to 1979. Other government statistics he introduced show that the inflation rate for this period was, on average, 5.88%. Therefore, all but 1.12% of the average past wage growth in this sector of the economy may have been attributable to inflation.
