If you have a tech startup you probably come from money already, are surrounded by people who come from money and are mostly going to talk to candidates who come from money.

The tech world is filled with wealthy people not wanting to believe that their wealth was a determining factor in their success. Having the social and financial stability to found a company and get money to hire people is the kind of thing that takes a degree of wealth and tends to attract people with wealth and repel people without.

I don't think people consciously choose to hire the rich kid, but the pool of people to choose from will be filled with rich kids.

If their child was able to go to an expensive prestigious school across the country and then an expensive graduate school instead of needing to work, have a larger network of friends and colleagues from those experiences, and can pay for them to have better healthcare and a nicer apartment in San Francisco because you're not able to pay enough then yes. It's more likely you're going to pick them and they'll say yes to you.
