It’s a solved problem as far as one can get given the constraints involved. As I said, if you don’t want to use that phrase then don’t. I’m not going to quibble over semantics. Human societies are far more complex than programming and the notion of “solved” means something different in the former than in the latter. Use whatever phrase you want. Just don’t think the U.S. system is in any way better. You are the one who brought up an anecdotal experience in favor of the U.S. system over Canada’s system.
