The concept of "corrected" assumes that someone knows all of economics, that he can correct for inequities, inefficiencies or unfairness in the system without ill consequences. That person of course doesn't exist. Nobody can perfectly grasp a system so vast and complex.
But we have people who still think they do know it all. Even worse than them not knowing all, they get to define "equitable," "efficient," "fair" and "ill" according to their own philosophy, pretty much guaranteeing a screwed-up result every time large-scale meddling is done.
In Soviet Russia pigs eat bread. Now a pig doesn't care that you added better ingredients to the wheat, let some yeast grow in it, and expended energy COOKING it! He would grow just as fat on grain.
But you see, the Revolution promised “bread and freedom”, and because it wasn't very forthcoming with the freedom, at least they could get you some bread! So bread was cheaper than the grain that went into it.
Thus pig farmers, being no fools, fed their pigs bread.
Socialism, feeding bread to pigs.
