zd: I think you are fishing for examples that are really none-issues. Your examples are issues that are part of day to day living and people find ways around them, such as bringing a family or friend to help translate, having community doctors who are cognizant of the communal needs etc.
I don’t understand your second comment. I am saying that advanced math is unnecessary in most cases and for those that need it, they can learn it.
Sam2: If the high schooler can’t make up his mind about what profession he will have, then why not teach it to him once he is mature enough to make that decision? Do you think that having learned the “basics” in high school, he will have enough time to pursue an advanced education before getting married? And if he does have enough time after high school(ie. he gets married a few years later), then he is already serious- so why not give him the necessary courses at that time?
