No not all talented scientists are independently wealthy or have the charisma to raise VC funding. What you're advocating for is the return of the era of the "gentleman scientist" where the only people allowed to do science are those lucky enough to be born into wealth (or some other privilege e.g. extreme good looks).
I’ve served as a reviewer for a couple of NSF panels, and one of the things I really liked about the program I reviewed for is that a lot of the proposals included collaborations with local trade and vocational schools to involve and train future technicians and operators in addition to researchers and scientists. I think that’s really important for actually succeeding at the technology transfer goals of NSF, and if I’m reading your comment it does at least partly address delivering direct value for a broader chunk of the population
If there is a large group of people who aren't benefiting they don't need to be involved in the funding and the organising either. It is a mistake to make research subject to political pressure if there is a significant political faction who doesn't think it is worthwhile for them.
