When I'm watching the SE and the prequels, some of the acting and special effects are so bad, I wonder how did they even got past quality control? Didn't George Lucas hire anybody to do that kind of work for him? Nobody said, um George, this looks fake, or um George, these performances were really lousy. Who ever did quality control on the prequels/special editions needs to get fired.

This question answers itself: because is so rich he can afford to surround himself with yes-men.

That said, I have nothing against the prequels. They suck, but so what? It's the changes to the OT that both bother me and suck.
