Well, as long as we are speaking in hyperbole, everyone needs to realize that K-12 CS education needs CS teachers, who are disproportionately not those international students who either get cushy jobs in SV or go home.
You're getting at the root of the problem: teaching in the U.S. is a low-paid, low-status position. Teaching in other countries is a decently-paid, high-status position. This directly translates into job desirability and ability to attract qualified candidates. I had some good teachers growing up, as well as a number of bad ones. The good ones all fell into one of these categories: 1) they were young and idealistic 2…
When they show up at parent-teacher conferences, they're usually mad that little Johnny is failing...even when little Johnny has literally turned in nothing all year, even classwork you gave them time in class to do. And hasn't retaken that test you've given him three times to do it at home. But it's my fault that I just don't get him a straight passing grade, despite all this. Or, their parents don't come/get mad when the kids cheat and get marked for it, etc. And, of course, often the parents of the best students do come, when they're the ones I need to talk to the least!
But, contrast them with my Hispanic students (particularly the Guatemalan ones, and the Mexican ones; the Puerto Rican ones are different). The Guatemalan students themselves are always so focused and wanting to pay attention, and the two Mexican girls usually are. They get frustrated at the Puerto Ricans, who goof off a lot.
Now, I don't see a lot of their parents, but that's more because they all work night shift (as do my students). However, if I offered (extra) credit for them to email/call, or show up to parent teacher conferences, every single one of them would be there. And usually they contact us, often through their kid since they don't speak much English, if their grades drop asking what the kid can change. It's very different in the attitude they have towards teachers compared to my American students (in general), and I think anyone who deals with a lot of them daily and gets to know them (one class is solely Hispanic students, so I don't have to worry about balancing language issues between them and American ones).
