I worked with NASA, and at the Air Force Research Laboratory Space Vehicles division (there satellite division). And yes, they have done some great things. But 9 out of 10 of the bright minds that have come up with these things, have been contractors from the private sector. Companies like CSC, Ball Aerospace, LockMart, Boeing, IBM, and a dozen other major government contractors. The private sector does things better... always.
Healthcare. How come when it's totally a capitalist endeavor, like elective surgery, I can get it done faster, cheaper, better. let's take eye surgery for example. I can use the best equipment in the world, top doctors, incredible comfort, and customer service for $800 an eye. A simple MRI is a pain in the ass to schedule, I was treated ruddily, and it cost me $2,000.
You need governent funding for advanced technology. The free market cannot realize that satellites would be a good investment, so they would never be the first to develop satellites by themselves without government assistance. NASA may hire the private sector to build or do research through public funding, but this is still government involvement in the economy because the free market can not provide such technology or goods by itself.
Healthcare is done more efficiently in a public system. This is do to healthcare's nature as a public good and a regional monopoly, resulting in market failure. America pays three times more for healthcare than Great Britain, do you think America's healthcare system is three times greater? It cant be, if Britain paid as much as we do they would have three times as many hospitals, three times as many doctors, and so forth. Below links are figures on healthcare funding (private and public).
Your opinions are incompatiable with economics. I'll introduce you to market failure:
Thats right, a very rightwing site suggests taxes and subsidies to provide things that the market is unable to provide efficiently. That is why you should be thankful that the government put a computer in your room, gave you the internet, and gave you satellites to communicate with. If the government did not research and develop these areas, you'd probably be reading a book right now.
