Insurance companies benefit from all those tricks: medical care billing is too complex to understand unless you have a full time team of people to understand it. Insurance companies have this team and you don't.

Vision doesn't work that way because enough people don't have basic vision care that they won't stand for the complexity.

So, the problem is that medical billing can be made too complicated for the free market to work - not the flat ~30% tax break?

NO, the problem is medical billing was allowed to become too complicated, and it is very hard to unwind that situation.

I'll contend (though of course there is no way to prove this) that if we hadn't had the advantage to company provided insurance the complex billing wouldn't have developed in the first place.
