David Green proposed somewhat similar ideas back in around
2000. Someone else (I forget who now) mentioned it again in a slightly
different form within the last year in an Artificial Life article. I
tried running an experiment implementing this idea using Tierra, but

Perhaps not..
One should not confuse economics with biological selection. It would
seem plausible that good economic times might lead to rapid evolution
of economies, such as during the recent Internet bubble for instance,
but not that it would have any influence on us at the genetic level.
