In the US, less than half of all college teaching is done by professors. The remainder are "adjunct" teachers, whose job focus is on teaching. An adjunct job tends to have low pay, is short term, and you sign away some of your rights under the labor laws. You have to re-apply for your job every semester.
Perhaps the real difference is how Germany treats workers.
The US has community colleges, that focus on teaching. In my state, the community college teachers are unionized, and teaching is treated more like a career.
Disclosure: I was an adjunct for a semester at a Big Ten university, more than 25 years ago. My spouse has worked there as a non-faculty researcher since that time.
German higher education is based in large classes with only an exam at the end of a class and no TAs, except at maybe the top institutions. They don’t need so many teachers, so they can treat them better.
It’s a system that we might want to try here in the USA, but it doesn’t coddle students.
There is also a USA non-adjunct job called "lecturer" that is meant to focus on teaching rather than research. But while better pay and job security than adjunct, it's still usually pretty bad. (Also not tenured).
