The government is and always has been the primary driver of science research funding. There simply isn't enough of a known payoff for private investors to bother and private philanthropists have never come close to making up the shortfall. Or perhaps more accurately the government stepped in because private individuals would not and the risk was falling dramatically behind the world in research.
