Update: s/majority/amount/
Used to be. The US government only funds 40% of basic scientific research now.
This is due to large increases investment from private industry, which now rivals the US government even for basic scientific research in addition to funding the vast majority of other research. US government funding didn't decrease, the pie just became much larger.
NSF regularly publishes detailed reports on US R&D funding. The trend toward industry funding eclipsing US government funding started in the 1960s.

1) The free market develops and sell products. 2) The government buys the products that the free market has produced. 3) Therefore the free market isn't viable without government tax money? Therefore socialism? Silicon Valley wouldn't be as successful without govt spending money on things it needs? Help me out here.
