That sounds like a very good idea. Over here all you need I believe is a phD.
Oh no don't misunderstand me. At that passage I only referred to school school. High School or whatever. I think our professors don't get to take any actual teaching classes, either. Though mostly I had no bad experiences. Except this one guy. He was not an actual professor. Just a guy pursuing his scientific career, trying to achieve professor-status I think (over here, you have to do a special scientific project to become professor, similar to how you have to do a special scientific project to achieve a doctorate - I think at least in the US it is different, professor is just some kind of title).
Anyway, I attended an advanced class on econometrics with this guy and he straight up told us that in his previous class on that, in the middle of the term, the students collectively got up in class and told him that they had no idea what he was talking about most of the time.

And it wasn't much better in my class. He just got his head so full of mathematics that he would jump the mathematical steps and just kept on drawing crazy mathematical stuff on the board, living in his own little frame of mind where it was all so obvious. I never have felt so continuously dumb in a class I took...
and they can never get fired if they suck, because tenure.
From I gathered, that tenure can not possibly worse than our professor status.
I have read about 'publish or perish' in the Anglo-Saxon world. That may apply over here as well as long if you are not a professor. But if you are..
As I recall there actually was a court case where they tried to fire a professor because he was just lazy and enjoying his time. The court ruled against it. Because independence of science. I think you can pretty much do anything if you are a professor over her accept ignore your teaching obligations or just live on the Bermudas all-through the year or show up naked in class or something like that.
There were several Chinese math professors I had in university, who couldn't really speak English. One of them was so bad I could literally not understand a single word. He just stood there facing the board the entire time and continued scribbling stuff on it. No interaction with the class, because his command of English was so poor it wouldn't have been possible. I had to teach myself the material on my own time.
Wow that sounds terrible

The worse I got in that regard was a guy who had immigrated from Turkey and who had a bad habit of swallowing crucial-to-understand-him-parts of his words. But it was manageable.
From my experience books played a relatively large role - in that they had all the assignment questions and readings that you had to do, write essays about, etc. I spent a couple hundred $ per term on books. From my understanding things are even worse now - books costing $100+ each.
Yeah nothing like that exists over here. If you have to read it, it will be ensured that you pay nothing for it. The rare exception are bundles of excerpts which may cost you 8-15 euros. But you rarely have more than two of those in a semester if you have them at all.
Another problem is the food costs on campus. Here where I work there is a Harvey's on campus - a fast food chain. There is another Harvey's, just off-campus, maybe a 15 minute walk from the food court.
But you do have cafeterias on campus, don't you? I know I have seen them. Any public German university has them (and there are mostly only public universities) and you pay about 1,50 - 3€ for a full wholesome meal. Whereas 3€ gets you fairly good quality. Though cafeteria food can also be a bit sucky. But mostly it is okay. And it is fairly healthy. No fast food.
My experience with American Highschool cafeteria food (two different high schools in two different states) was so abysmal it still seems like a bad stereo-type to me. The older kids with cars got their food at a fast-food-joint near by and it
was better.
It's blatant exploitation of students and nobody's really complaining about it (loud enough).
Complain to your boot straps, man!
