that only happens on reddit

But the same asshole still owns all the houses when the tourists leave. Just because they are gone doesn't mean the locals will get anything.

Mass tourism machines like cruise ships have several layers of issues to them, but they are also the economic centers of many marine locations that wouldn't be what they are without them, but that's also sort of the problem with them.

Very bad example for your point. The port towns visited profit very little from the cruise ships. People sleep, eat and shop on their ship, the local economy sees almost no benefit but the streets are clogged by their day trips.

anywhere remotely interesting to visit is packed from dawn to dusk

That's a bit of an exaggeration, I've been having the time of my life here in vietnam, just ask the locals for some ideas and check Google maps for traffic to avoid the one everyone is already going to, and you'll have a beach, mountain, beautiful twisty roads along rivers and mountains, local swimming hole, etc to yourself and like 3 or 4 locals who you have to flee before they invite you to lunch, introduce the whole family, then dinner, then to sleep at their place, marry their daughter, etc.

Its not an issue of too many people, just everyone goes to the same exact place because some influencer recommended it.

Add into it the cheap air fares, etc… and it opened up the world to the average Joe, who has not the best manners or realistic expectations all the time.

Should only rich people should be able to travel? People with more money also have more manners?

add in the fact there are too damn many of us on this planet that anywhere remotely interesting to visit is packed from dawn to dusk and it gets annoying having to wait for things all the time

Just dropping this here: Debunking ‘overpopulation’

There is a football stadium near my home. Those fans should all stay home. I bet some don't even come from my city. They make public transit busy when there are games! Why do we have to share this world with others?!

EDIT: I don't want to seem like I entirely disagree but again, capitalism and mass tourism. Social media is also to blame. Societal hype. But if you think you have to wait everywhere that's "worth" visiting, maybe you can try to spread out. We don't all have to go visit the Eiffel tower or the same national park in Croatia.

there's things that are designed for visitors, and then there's things that are designed for "vacationers" who spend way too much fucking money to just sit around not actually enjoying things for some god forsaken reason.

the former is great, make things enjoyable regardless of where you're from or how long you're staying.

Weirdly, chinese tourists in China are completely different from chinese tourists outside of China, and the effect increases the further you go.

I suspect the ones with money to travel further and to wealthier countries are the kids of new money petty bourgeois who are used to not giving a shit about social consequences.
