"Cling to your ideas that someone working on an island which roughly costs 30% more than mainland France to reside (if not more) equates to what you would leave a server in France."
That's not really the point is it? All employees should be paid a "living" wage by their employer. What's a living wage will obviously vary by locale as well as the services provided workers by the government (e.g., healthcare). That we have developed this bizarre custom in the US whereby restaurant service personnel are paid a de minimis amount by their employers and their income largely left to the whim of the customer is not something to be exported as a positive model, imho. At the end of the day, it is bad for the customer and the employee. It only benefits the employer. If a business cannot or will not pay its employees properly, it should not and will not remain in business long (Walmart excepted, of course).
Some restaurants in the US have tried to move the to a service compris model. I undertsand that this concept is not being widely adopted at a rapid rate, but one can hope. And, while I defer to the active caterers on this board, it has been my personal experience that catering service personnel are not tipped in a traditional sense in the US. Why should it be so different in restaurants?
I, for one, would rather that the restaurant owners charge 20% more on the menu and pay their employees appropriately (a living wage) than the current tip system. Apparently, now in St Barths one does not know if one is supposed to tip or not. While this may not matter to some of you, especially if there are only one or two in your party, we are 4, 5 or more when we dine out. The extra $100 on a $500 bill is enough to make me think twice about whether we dine out or in on a particular evening.
I suspect that the reason that the tip system has lasted so long in the US without complaint from employees is that it allowed for somewhat creative tax filings by the tipped employees. Now that the use of cash has diminished significantly and thereby reduced the ability of a tipped employee to be creative on reporting their income for tax purposes, I suspect that the receipt of a large portion of one's annual income as tips will lose its allure.
