Oh believe me... Coming from the US, the summer between my first and second year, I was compensated 5k for three months of work. When I first heard what was standard in NL I was shocked. Then again, I was also paying 50k per semester for school, soooo yeah, take your pick haha. I wouldn't say slavery, more like indentured servitude. Anyways, I make it my personal goal to give our interns as much of mine and our senior devs' time as possible, as well as support after their internship is over.
I would hope you'd make more than $5k working in software for a summer. I was making that a decade ago wearing a hard hat and pushing a broom in a power plant on my summer breaks...
