Does that surprise you? As far as I know, they are underrepresented in medicine, finance, and law as well.

There is more mobility than most people realize, but it's not like employment approaches anything near a random distribution. Given the potential advantages of being born into a wealthier class (both hereditary and non-hereditary), I would expect to see underrepresentation.

It doesn't surprise me at all. Being in tech usually means starting earlier than medicine, finance or law and if you're poor you likely had less opportunities to own or use computers. Access might be provided through school or libraries but you won't generally have access to installing programming languages or anything.

While it didn't surprise me I'd still like more surveys and insight to exactly how hard it is for the lower class to join the tech and start up booms.
