Unfortunately "the rest of us" = American tourists and American's don't seem about to change being the worlds tippers, so a change in the destinations culture to no tipping due to livable wages probably won't stop American's from doing their best to keep right on tipping.
In my mind if I had a time machine I think if I went back a ways to Cozumel of old there was not much tipping until American's showed up. As a nation whether tipping is prevalent in a location or not we tend to over time wear down their no tipping customs and change the landscape to a tipping culture. Everywhere you go Americans are tipping non tipped people. There are places in europe where service industry people get a living wage and tipping is supposed to not be expected, but every few years I go back I see tipping creeping more and more into their culture thanks to American tourists. It usually starts with a strict no tipping policy, then gradually the culture accepts small change left over "rounding up" is acceptable, then it turns into "for exceptional service" and eventually 10% and then 15%, 20% becomes the norm.....
I recently returned from Fiji which is a non-tipping culture. Everywhere there are signs where you're staying, little placards on the night stand, little reminders placed here and there gently reminding you not to tip, please don't tip, please please do not tip! Well... I couldn't help myself and tipped my dive master there, he had no problems taking it "down low on the sly" and gently easing it into his pocket away from any observing eyes of management... obviously I wasn't breaking any recent new ground there with my tip. We Americans will ruin it for everyone else, it's just who we are as a people.
