rediculousagree that career is not just money. but you need to get the facts right.
an average first year associate, note just an average one, gets between US$200-300k per year. And i don't believe an average engineer gets even close.
on the other hand, yes i-bankers works long hours and overnight is frequent. so it's definitely not a decent job for young girls, especially if you care more about your beaufy and health.
first year associate is usually an MBA
in top US MBA schools, to get quarter million annual salary is considered very high already, not many people will get that opportunity.
