That's my biggest problem with socialism in general, it replaces "This person is willing to pay me more" with "I just like this person better" or "This person has the right connections." Of course there are situations when "This person is willing to pay me more" isn't fair, but those other things are even more unfair.

The nice thing about the highest bidder gets it is that is creates an incentive and resources to make more of whatever "it" is. Capitalism isn't meant to be fair, it's meant to make more. That doesn't always work, housing is a good example of it struggling, but it at least tacitly tries to solve the core problem (shortage).
