Really? Does white people baiting have to become totally normalised? It’s not like East and South Asians aren’t over represented in VC land.
(Exception: if you are Chinese and your investor is Chinese and you have a personal connection to that investor you can sometimes raise money on "Hi I have an idea and trust me." This is a recent development and comes from the massive amount of Chinese capital floating around these days, and is sometimes not actually the best move for your startup.)
I know YC is a relatively small part of the VC ecosystem but it’s pretty influential. If the VC ecosystem is as racist as you say there should be plenty of opportunity to make better returns out there for some enterprising VC.
There are a few other VC firms that similarly work hard to avoid missing promising founders of minority backgrounds, but they are still the exception rather than the rule. Over time, the "rich, dumb, and prejudiced" folks will get flushed out of the market, but that's over a lot of time. Besides, they'll probably just get replaced by a different set of prejudices - nobody can be 100% unbiased, you can only hope to replace biases that are useless and arbitrary with ones that are somewhat more useful.
It usually takes 2-3 years before a typical founder can get seed funding and even think about hiring employees. During that time period, they are funding the company themselves, and doing all the work themselves. Yes, they usually draw a small salary once the company is VC-funded. By that point, ~95% of founders have been flushed out of the market and failed.
There are a small minority of people who can raise VC on just an idea because they're white, wealthy, and went to Stanford or because they're roommates with a VC's daughter or because they're an unusually slick salesman who can swindle lots of people. I would highly recommend not working for these people - or really, any founding team who did not build and sell the initial version of the product themself - because they generally do not know what they're doing, and these startups become a miserable experience for the employees. But they are, I'll reiterate, a very small minority of founders. They are a somewhat larger minority of the founders who can hire employees, because getting VC investment automatically puts you in the pool of startups that is looking to hire. That's an information distortion between the viewpoint of employees (who only see the startups who have gotten at least to the first funding round) and founders (who see all startups, including the ones that struggle for years to get their first revenue).
