They do too. Is not as simple as having money or not, the social fabric is the base of healthy neighborhoods and tourism is really invasive against that matter. I said a bunch of reasons there. The visitors should be aware of that. Why would we want to have more money if we don't have a place to live that we can call home? Or if those who are "pumping money" are making our life's more expensive while our salaries remain the same? I don't think you are addressing the problem from the vision of someone suffering the gentrification.
