Meh. If you have two coins that are nominally worth the same but one is actually worth more - because it can, in a pinch, be melted down for a valuable resource - I wouldn't call this the bad driving out the good.

Of course the point that bad behavior may give a higher fitness score is still true.

I also like the idea of lemon market's in this context: https://en.wikipedia.org/wiki/The_Market_for_Lemons In short and very simplified: if the customer cannot tell the good products from the bad products he will not pay the price of the good products and so the good products disappear.
