I mean, in a lot of ways it already is. More and more people aren't taking theses jobs that pay shit, and yours constantly seeing places fold or be understaffed. It's also a little disingenuous to use the extreme as an example. The vast majority of tourist destinations (relevant because OP) are not paying below minimum+ tips. It would be helpful if OP Said where they were going but assuming it's a popular destination, they don't need to be heavy handed. It's also misleading to paint it as black and white "assume tipping 20%" everywhere is bad advice. There is no expectation to tip for over the counter service, take out, etc. That is a fairly recent evolution and one that is already backfiring. If OP isn't sitting down in a restaurant where they have a server waiting on them for 30-60 minutes, they are probably absolutely fine not tipping. 15% is also still acceptable, 20% is excessive unless the service was absolutely excellent.
