"You're going to end up with a bunch of rich white dudes as founders (because very, very obviously the other way that people can afford to take smaller checks is if they have a lot of money in the bank)."

There are many founders of various social identities who are not rich yet have managed to succeed with bootstrapping or small seed/accelerator investments because they are capable.

To assert that some people are inherently advantaged or disadvantaged as founders and/or entrepreneurs based on such factors as race and gender is the definition of prejudice.
