Earlier quoted context omitted.
Sorry if I wasn't clear, I'm not talking about zero-sum (which should be similar everywhere), I'm talking about Universities becoming easier in USA much faster than in Europe. Example: https://www.theatlantic.com/education/archive/2015/01/same-p...
How do European professors and universities avoid grade inflation? Are their incentives very different?
In general university costs money, both to the Government/State and the student, and thus incentives are somewhat aligned for both parties. Also, student loans are NOT a common thing here... When I was at uni, the cost of the studies was about 1000€/year (500€ for me as my parents have 3 children), now it's about 2 to 3k€/year, but it's still something somewhat feasible. That's Spain, in Germany for example it's free.
