Mate, I grew up in a highly touristic country - Portugal, specifically in Lisbon - which is now on its second wave of being "discovered" as a Touristic place, and the same kind of shit described by the previous posts which happened to Algarve (the region in the south) during the first wave that sold beaches & sunshine is now happening in the second wave that's selling culture & old-buildings in places like Lisbon and Porto.

I've also lived for almost a decade in Amsterdam and the exact same shit was starting to happen there when I left (and it became much worse before the locals rebelled and elected a city hall that cracked down in it).

I've also lived in London were the same shit was happening, though slowed than in the other cities (maybe because it's a much larger city), though they do have the worst housing bubble in the whole of Europe.

I've actually seen this shit happen before and am currently seeing this shit happen right now (I'm back in Portugal, though not Lisbon, but my parents still live in the outskirts of it), so am not just pulling wishfull thinking opinions out of my arse.

Methinks you've never seen first hand over a couple years how Tourism can destroy the character of a place as locals get kicked out to be replaced by AirBnBs, so old corner grocery-shops don't have enough customers and end up replaced by stores selling knick-knacks to tourists, how more broadly you see phenomenons like traditional local restaurants being replace by the kind of restaurant you find in international airports or theatrical "typical" restaurants and how all other industries start getting pushed out by Tourism because cost of living (especiallly housing) for people who work in that city is too high for local salaries and the rents of commercial premises get too high.

It's all fine and dandy when you're a cottage tourist destination and Tourism is mostly a side-show next to all the other Economic activity there, but when a place becomes a major tourist destination there are all manner of massive nasty side effects of it which amongst other things hinder all other economic activities (as everything becomes much more expensive there, most notably housing) and then your country is 20% dependent on it, ready to be fucked next time a vulcano in Iceland coughs up a proper ash cloud and stops most flights in Europe for a month or, more likely, a big world Economic downturn comes and people cut down on unecessary expenses such as vacations abroad.

As it so happens most tourists go to "major tourist destinations", which is were Tourism is most damaging, so that experience of the meme is indeed the most common.

Because you seem like a person wanting to learn and not a bot, here is a video by John Oliver, 6 years ago, about the actual local situation in Everest.

The causes will be varied, and the housing market is not threatened in Everest because tourists don't use houses in Everest the way tourists use houses in Europe (Airbnb), but they're is always incredible damage in whatever thing, local owners use tourist money, to fuck local workers about, not caring for the Shit and damage left behind. In the case is Everest, that Shit is literal. In other places, that Shit is off-season ghost towns, underfunded schools and local necessities, and corrupt local politicians.

This is just capitalism by design, it's not unique to tourism. It IS the owner's fault, not the tourist's, but the tourist buys the meal that the local no longer can afford, because tourists by definition go be tourists in cheaper countries than their own. Do you understand what that means? The locals that serve the tourists, get so little money in comparison, that it's not even funny.
