OK, if you could have both those things, yes, people would go for that.

This depends on how much of a selection process there is in adoption.If rich folks
are more likely to adopt healthy fit looking children, then
the fact that an adoptee's parents are rich would also signal their fitness.
Of course if this effect is weaker than the direct parent effect in our ancestor's

environment, your conclusion would be right.

The point was that we mainly want a signal about the average fitness of awhole
genome. You could have one or two specific bad genes even if
the rest of your genome were great. Consider Lou Gerig's (sp?) disease.
What a shame that such a fit person suffered from few bad genes.
