I wouldn't say majority but a fair bit. man, most of the kids i've known in my life had waay more than me growing up in terms of stability, family, $, friendships, lack of abuse/depression/bullshit etc. Some of them are gonna be be doctors/nurses/c-suites/engineers.

Most of the kinds in engg school come from strong middle class families. They're prob gonna follow the same path.

For sure, the richest dude I know, my age, prob is worth a few mill rn and could be 10mil within the next 5 years. He's prob gonna hit 20+ by 50yrs old I imagine. How? expanding family business. Hard worker, very smart and fruugal kid but he was given a silver plate to run off of.
