Tourists have far more money to spend than local residents, since they're not staying for long. So they tend to empty heavily touristic cities from their residents. Think about it for a moment: would Paris without cafes and french people still be Paris?

I think a lot of people would consider Paris without the French heaven :)
Jokes aside, a lot of holiday spots are popular regardless of the lack of locals. Paris without the French might not be the Paris you know and love, but undoubtedly it would still be popular.
