I do not like the imagination of such a concept but I rather prefer it to a total capitalism.
Why?
I do think that there are some tasks that are better performed by the market and some that are better performed by a state.
Was it a good thing when firefighters were private enterprises and your house would just burn down if you weren't able to buy their services?Yes, it is. <- Notice that I used the present tense there. I did so intentionally.
If you lower all the taxes (health care, social security, etc) especially poor workers wont get more for their work since the market will immediatly adopt to the situation and lower wages to the new level of minimum accepteable compensation. Taxes on wages are also a gurantee for a minimum of social security.
Taxes colected are bad managed in a degree that is unbearable. But I'm not ready to abandon the concept for a "If we just would have the REAL market" idea.
Well, I've got some bad news for you then, because by my reconning, we are going to get a real free market within a decade whether we as a people are prepared for that or not.
