Is the unrestricted capitalism model the best fit for America?

I think it is a pretty fair and decent system. You pay for what you get, minus imperative services such as protection (law-enforcement) and an army. Everything else (education, health care, fire department, etc.) will be paid for by you through either insurance agreements with your employer or straight cash. Pensions, welfare, and all other forms of social assistance will be abolished. This will promote responsibility and encourage families to have savings for emergencies. I think this is the most fairest system and the best way to recover our nation, what about you? If you are against this model, why? Do you have any valid counter arguments against fairly paying for what you use?
