The job of the high paid people in finance at prestigious firms is to look nice in an expensive suit. Know many people in tech with those qualifications?
I'd be good at it but I won't get hired cause I didn't go to the right boarding school.
Tech has its barriers too. Most people I've met in tech come from relatively rich families. (Families where spending $70k+/yr on college is not a major concern for multiple kids - that's not normal middle class at all even for the US)
