I have lived in the Middle east (Iraq, Iran, Saudi Arabia) for ~10 years. I have also lived in the US for 10 years. Infrastructure in the Middle East (roads and bridges, public transportation) is actually better than USA. Poverty is lower because the government has oil money and everybody (citizens) is on welfare. Some countries like Iran are more educated than the USA. Saudi Arabia has the biggest supercomputer in the world and my college friends who went there for grad studies got duplex villas to live in whereas I toiled on 20k annual salary in the US. Of course there are issues- human rights, minorities, cultural issues and racism- but it's not like those problems don't exist in the US.

The data centers are there because customers are there. If you stumble on to a twitch streamer or tiktoker from Dubai, you'll find there's are thousands more.
