I've lived in numerous developing countries and while I can certainly think of a number of places where gentrification pushed locals out of certain neighborhoods, I've never seen expats doing this on the scale I witnessed in the US. It's a complex issue. First, expats are not a homogeneous bunch. In a lot of developing countries in SE Asia, for instance, the expat communities are not made up of large numbers of truly affluent people. Generally, the expats who live in the expensive buildings/houses and employ local help (maids, cooks, etc.) work for large companies (in higher-level roles), embassies and NGOs. The majority of the "digital nomad" types don't actually live affluent lifestyles in my experience. Sure, they make a lot more than the locals, but they're not spending $3,000/month on an apartment in Bangkok or HCMC. This doesn't mean they don't have an effect on local economies, but there just aren't enough expats in fast-growing, fast-developing cities to cause negative gentrification effects like you see in places like the SF Bay Area. Second, in some places, like Bali, the economies are totally built around the presence of foreigners (expats, "semi-permanent" foreign residents and foreign tourists). Take them away and the locals suffer massively. Bali has been absolutely bleeding because of COVID. I guarantee you if you asked the average Balinese person if they want "normal" to return (which means a heavy foreigner population), they would tell you "yes x10000000000000". Finally, a lot of developing countries, while still poor, have fast-growing economies and there is a lot of development taking place that is driven by the growing wealth and urbanization locally. I worked in Phnom Penh (Cambodia) for a time and while you could see the effect expats had in a neighborhood like BBK1, other neighborhoods were clearly changing more as a result of the growing wealth of locals and increased urbanization (people coming from the countryside to find opportunity in the city).
