Have we veered way off the topic?
I don’t think the average IB candidate is trying to wring the last 5% of value out of their school or is typical of anymore than 0.5% of the college student population, Who grabs that golden ring is much more a function of personal qualities, from family connections and poise to interests (including polo or whatever upper class sport you choose) as well as just an incredible work ethic and well brains.
If I have a starting salary in the $150K range under 30, I can pay off any amount of loans I chose to accumulate.
Similarly, I find the Duke study to be limited in value by the very fact that these are Duke students who have already passed through the 1% college admission hoop, and to be fair, face very small income losses by switching from STEM to liberal arts majors, as a matter of fact Duke carries more weight for an art history major than an engineer or math major. A second tier state school student who switches from engineering to art history may lose 50% of their income.
I think the yurt dwellers of Vermont have never considered IB and hundreds of colleges do not send people to IB or these high end jobs, they turn out perfectly qualified middle of the road people for the middle 50% of jobs.
I think a Big Data grad who can’t program really, really well is bound for companies that say invest in Big Data, not those looking to implement v1 of BD breakthrough software. Similarly, your compliance team may need cream of the crop, but many other companies might just need some people who can implement some compliance protocols.
Reading, writing, 'rithmetic + speaking, programming (light) + people skills -> most jobs
The more selective the job, especially with commensurate high pay, the higher the standards you can put out, and the more you may really just be looking for very core intelligence (multifaceted)
Obviously anyone with the smarts to fill those positions you have could probably major in just about anything you want them too … maybe they would segregate into math, programming, legal buckets … so obviously you just don’t care. They are very trainable and will be whatever you need to be in a year or less.
The ordinary humans who have most jobs need those 4 or 6 or 8 years to get up to speed … and accumulate the more mundane knowledge and at least a familiarity with the new stuff they are likely going to get hired for (the 50 year olds will keep up with the more mundane stuff for another 20 years). Hey, Joe, you are young, have you heard about Big Data? Oh really, you took a class or majored in that at EW State College. That’s great … we have a vendor coming in to show us some Big Data stuff next week, why don’t you join us…
