I would also add in the complexity of US elections. Depending on the year you have multiple federal, state, and local positions. Add to that ballot initiatives and it’s not difficult to have a ballot that is both sides of an A2 sheet of paper. Even with all that, I’ve never had to wait more than 30 minutes. Also, while Election Day isn’t a federal holiday, ~40 states have a legal requirement that employers give employees time off to vote. (Not in the OP’s initial list, but something people generally bring up without knowing the facts on the ground)
