Simply or simple?
Just because you guys have a fair working wage for everyone, universal healthcare, free universities, actual time for vacation, family leave, and better cheese doesn't mean you should hate any part of our culture.
You should just pity us.
I used to feel bad for Italians because of your politicians. Now I envy you. Sigh.
Of course hating the American tipping culture does not mean that we hate Americans.
I love USA. I spent some of the best moments of my life while being in US.
We love most parts of American culture.
I actually hate just the tipping and the fact that money is considered a measure of the value of everything (humans included).
I also discovered recently another nasty thing, the existence of HOAs in many residential areas.
About Italian politics, better not to say anything. We are going worse at every change...
Luckily they have much less power than in US. So despite a bad political class, they cannot make too much damage.
Sorry for going off topic.
Back to tipping.
An international destination such as Cozumel should find the way of accomodating properly both tipping and not-tipping tourists.
This means increasing the wages, so workers can live without relying on tips.
So I think that Americans, when abroad, should also evaluate the option of stopping tipping entirely, or reduce it substantially, and only when getting an out of ordinary service.
You are not in US. When you go to Rome, behave as Romans.
Exporting your nasty tipping culture to other countries do nothing good to locals. It is way better to get a good, guaranteed wage from your employer, which comes in also when your are ill or in paternity/maternity leave, or during your holidays.
If your earnings come mostly from tips, you do not earn when not working, for any reason.
This is terribly unfair, people do not choose to be ill, and getting a good amount of paid holidays is very healthy.
Exporting your tipping culture destroys the salary protection of workers.
Stopping tipping will have a short-term bad effect, but in the long term the working conditions will improve, aligning with our European standards, which provide good protection to all workers.
