I don't have a lot of knowledge on this subject so this may sound trolly but it's a legitimate question.
How do you solve things like privatized healthcare?
Look at the US: Leaving it up to the "free" market sounds fine for apples and oranges... buy what about when you can only get treatment through a doctor and it costs $10,000.
If you can't buy cheap supplies in bulk for the entire country and without proper regulations you end up getting fucked at every part of the supply chain.
I actually agree, the reason why privatization doesn't end up working is because at some point it's no longer really private but enforced by government granted monopoly using public funds. This is specifically true for copyrights and patents on medicine or technology used in medical devices. Socialized medicine can be better when the government is negotiating with these patent holders and can threaten to use generic (unlicensed) drugs, as a result people in the US pay a higher price for drugs because they don't have a real choice to use unlicensed generic drugs.
