I think the government at times uses tax money well, at other times it does not. It has it's share of inefficiencies and dysfunctions. I think also that the private sector, especially large corporations, do a generally good job of allocating economic resources, but are full of inefficiencies, dysfunctions and inequities. I'm simply not willing to indulge in generalizations on the order of "government = bad" or "private sector = good." There are a wide variety of public goods/service, which I'd be very hesitant to turn over to the private sector, for a variety of reasons, and a wide variety of goods/services I'd be very hesitant to turn over to the public sector. Provision of health care is not one of them, because as I've noted repeatedly, countries that DO have a much larger role of the government in healthcare delivery do so at a lower cost, with better outcomes, and higher public satisfaction rates.
I see the issue as complex, whereas your posts lead me to believe that you don't, and that, rather, you have a pretty simplistic understanding of what is, in my opinion, a complex issue.
