The direct fix is not that hard. I’m pretty sure the laws are already there, they just need to be used. Block mergers that create companies with massive market share. Break up monopolies. Severely punish price fixing.

The real question is, why doesn’t this happen? And answering that gets you to the real, difficult problem: the government doesn’t want to do these things because the government chiefly operates to serve the rich and powerful. Solving that is quite difficult indeed.
