Well, if everybody else thinks that programmers make $200K/year, there's a chance that somebody might consider paying $200K/year. That seems like an incentive to me.
Nope. Lots of places can't pay that money. They'll still try to interview and hire people but they can't compete.
There is a very wide range of salary, skill and experience in tech. A single figure is not of much use. If anything it might be ruined by the vast majority of cheap companies (i.e. outside of Google/Apple/Facebook/... )
I don't think that sounds very plausible.
