I'll say the quiet part outloud. It doesn't work. Military, Health, Social Services, Justice, Power Generation, and Regualtion are all things that at their core function should be done by the state at a cost to taxpayers (in a progressive way). The private sector can make widgets and sell junk, as long as they can do it without harming people.

I know it seems simplistic, but generally the private market is full of corruption the poor can't really avoid. So they just end up victims to it.
