the trend i see is that the most ambitious people do startup and degree(s) matter less as time goes
maybe a quantitative measure like Z = asset_from_work_now / cost_before_work_then where cost_before_work_then include tuition, rent, etc ... work can be defined as wall street, lawyer, plumber, startup, etc
Z for googlers can be in the thousands to millions, while Z for wall streets might be in the tens or hundreds ... big difference
or course Z can be negative (bankrupt+debt) ... but the huge discrepancy of Z value only reinforces my point, only the brave and ambitious dare to walk the uncertain path; the rest only follow thru the proven, safe path
These three industries all have one thing in common, they pay well and they only require a Liberal Arts degree. My sister graduated from Harvard a few years back and I'd say that every single one of her friends I've met works in one of these three industries. Their conversations of others I haven't met indicate that these three professions are the norm for all their classmates.
Perhaps Stanford is different and perhaps CS majors are as well. But the major trend I see is that the most ambitious people from the most prestigious Universities are going to the places that pay them the most.
