Basic research is where the real risks are taken, and the majority of it is govt-funded.
Before you start listing those items, do check the history to make sure there is no public funding involved at any level.
You should also check your facts before stating that “every significant technological innovation of the past two centuries come[s] from a capitalist country.”
Remember, the U.S. isn’t really a “capitalist” country in the sense that our government provides for the physical, legal, social, and military infrastructure without which most of this “innovation” couldn’t or wouldn’t take place. If left to it’s own devices, the private market would not be nearly as innovative or productive as it’s been. Not only that, but the vast amount of money spent on public education (at all levels) is also a govt-funded “gift” to the private sector. Then, there’s the govt-funded R&D…but don’t let yourself get bogged down in facts or anything.
