I really doubt that would work out. Especially depending what you mean by "wealthy". There is probably a sweet spot in the income bracket where that would do something, but those people would not be considered "wealthy" by most definitions.

I know people who fall into the 20% tax bracket, living in London, who are still able to do a return flight to somewhere in Europe once a month.

How do you prevent people who otherwise live frugally from flying frequently?

Traveling these days is incredibly cheap. People can save up enough to travel around SE Asia by working restaurant or retail jobs if they put their minds to it.
