Quite often you see people saying “tourists need to go home” or “we need less tourists” and there are some valid issues with how people can be, but overall, having tourists is a good thing. It shows that the middle class actually has means of traveling. It also tends to stimulate a local economy with additional revenue and can offset taxes for locals through hotel and other tourism fees. Those that do travel also tend to develop a broader world view then being in their own little sphere.
A reduction in tourism means that only the rich will end up traveling, and everyone else will be stuck only in the place they’re born, relegated mainly to pictures and videos “of a far off land” and will foster deeper divides of “well that’s just them over there” instead of getting to experience it firsthand.
Tourists are good for the country and for tourist based commerce, but overtourism hurt the local residents. Overcrowding, traffic jams, “normal” shops fade out for tourist shops, food prices goes up, housing is unaffordable for the local population all because tourists pay more. Increase on tourism related job which usually pay less for their workers. These workers can’t live in that area because it is too expensive and used by tourists.
