> In Spain, Germany, France, Italy, etc if you get a degree in STEM it means you put a lot of effort. [...] But the requirements to finish the degree have not changed so drastically as in the US so going to University is quite a good choice.
TLDR: As a Spaniard, I strongly disagree. Neither our universities as institutions nor our teachers as individuals have much incentive to (fairly) fail students, whereas they have many incentives to (unfairly) pass them. As a result, the level has dropped significantly in the latest decades.
The requirements in our degrees have plummeted since 20-30 years ago. Seriously, check exams from 20 years ago for ANY subject that was taught back then, and compare them to last year's. The difference is staggering.
There are several reasons for this:
First, because the level in high-school has been dropping similarly. Students get to the university with a lower base level, and hence they cannot be taught at the same level than before.
Second, because more and more people go to uni as time passes. This also drags down the average level of the average class (with respect to when the uni population was composed mainly of good and MOTIVATED students).
Third, because -contrary to what's been said here- our universities gain significantly from passing students. For one, each degree taught by a school is evaluated regarding the percentage of students that finish the degree in a set time, percentage of students that quit, and percentage of course passes [1]. This is the main evaluation of "quality" of a degree, and not hitting the set goals will lead to the degree being dropped.
Also, teachers gain nothing from failing students. Most will just accept it (because most know they really don't deserve to pass). However, some will complain. Very loudly. And handling such complaints is a huge time-sink not just for the involved teacher, but also for the department and the School itself. The easy way out is to just pass people. Many teachers openly admit that they pass lots of students who they don't think have achieved the goals of their subjects. And many students themselves admit it too.
