Sure. But one studied business (and got a decent paying job) and the other one went for a PhD in chemistry. Now: two siblings were female and the one going for “becoming a secretary at a large automotive company” like literally did not know what to spend all the bonuses and salary on - she was living at home until getting married and saved rent as well. She can always work part-time in her job, probably has a “large house-down-payment” on her bank account and is in a really relaxed situation. Studying 5 years (paying rent, not having income,...) and the fact that university graduates “have a harder time getting into that large company and even get less paid than factory workers” was not exactly obvious at the beginning. Due to the workplace protection in place and pretty strong union representation in “blue collar jobs” it often doesn’t make much sense for women to pursue a university degree from a financial perspective. I am very frustrated about that.

Second example - well, the PhD postdoc survives 2-year contract over 2-year contract while his younger brother just loads just more cash than he can carry.

This does not hold everywhere - both “younger siblings” work at a large industrial company that pays well. It’s just 100x easier to get a job that is paying well with mediocre grades and an uncle than with an engineering, business or science “summa cum laude” university degree.

Really crazy how that turned out. Many more similar stories from my siblings and their class-mates.
