I didn't state it strongly enough. Startups are for the rich and privileged, by the very nature of their mechanism of success. Lottery tickets, playing blackjack, rolling dice, are things which should only be done with what you have in excess. I don't think it's YC's responsibility to even societal odds. They are downstream from that position and simply consume and profit off those who have more than they need.
YC is a business entity not a non-profit organization dedicated to wealth distribution. You're asking it to do a job outside its core responsibility (profit, survival). If you want to make the argument that YC should up it's funding, that argument has to establish itself as being strongly in the interest of YC, otherwise it doesn't make much sense.
