I'm guessing your principle source of information is the UK press, and you have little experience of living and working outside Europe/US/Aus/NZ.
Two aspects to your post. Firstly the Entitlement. Agreed, there are hundreds of entitled Brits, many of then in their 20s and fully deserving Chav status. Plenty of entitlement amongst the 30-40 mums one sees doing the school rum in fancy cay, dressed in floaty beach dresses or yoga wear. Thankfully these are a small minority, but one that the UK press focuses on and hence the horrible trash TV shows.
The existence of the entitled chav Brits are not the fault of the Dubai system, there are plenty of decent Brits and nationalities there too, from many many countries. When our goddaughter was at school there in 2010-15 there were around 25 in the class. No more than three came from the same home country. All the children and parents rubbed along nicely.
Now consider the human rights you mentioned. Walked around Dubai staff accommodation recently? My OH does as part of his job. He also has recent experience of the project management sector in the following countries, Kuwait, KSA, Bahrain, Oman, Egypt, Jordan, India, Sudan. Turkey, Chad, Mali. The country with the most impressive record on workers rights, welfare, and living conditions is Dubai/ AD. Nowhere else in the region comes close.
The place may not be a perfect liberal democracy, but it just WORKS.
