You can study something somewhere, say at a trade school, or night school, but not at a university and we are talking about university education. We are not talking about secondary education or vocational trade schools. Telling a kid who wants to go to university that they can't do that because their test scores are too low but there is a great refrigeration maintenance vocational school that will accept them does not mean that university education is available to them.
In the US if you have a checkbook and pulse there will be a university that will accept you regardless of your test scores. Not every university, not MIT, but Joe Bob State will take you. Universities even offer remedial education programs so those who are barely literate and innumerate can still enroll, stay longer, and graduate from the university. In Germany you would have been routed out of the system and rerouted to a vocational school, which you are lumping in with a university education by using the vague word "study". "Anyone can study". Well, anyone can study at a library in the US, too, but we are talking about admission to university.
