I'm not sure what country you work in, but in the US we are so short on STEM degreed individuals that they get jobs by just showing up. STEM is by far the best field to get into in the US currently. I am constantly struggling to find qualified technical folks to hire because there is so much competition from other employers. It's a sellers market right now - if you're selling your STEM services, lots of us are buying.
Try reading what I wrote and who it was directed to and you'd realize we have the same views.
STEM degrees are in high demand, so when you get done your undergrad, get a job asap (it's relatively easy compared to other degrees). That's what I am saying.
Raux is suggesting going back to school for another 2 years and getting your masters, rather than just hopping directly into the workforce. In most cases that is a poor decision and you won't see any financial gains by doing it.
