I'm not sure I agree with you assertion. John Carmack is a notable college dropout who has been working on space travel. Capital is the only thing holding anyone back from working on those things. The reason you may see more scientists and engineers having access to the necessary capital is because they generally have that extra special drive to focus on that subject matter which excites investors to bring forth the money to make it happen. Someone with the same drive, but without a degree, will probably go just as far – they are a very rare breed though. Any random person who wants to just start a business, any business, can go to the coffee shop and start working away. They don't need capital from anyone. That is why people working on big problems are few and far between. You have to really want to work on space travel, or whatever, to put forth the extra effort to find the already rare investors.
