I visited Riyadh once, for work, in 2015. I can’t comment on salaries, healthcare etc, but there are a few things about the place which stick in my memory:
1, Restaurants have two entrances. One for men, the other for ‘families’. Women are only allowed in the ‘family’ section and only when chaperoned by a man.
2, There are no cinemas, and no theatres. Dens of iniquity, apparently. And no alcohol, obviously. Some Western expats who live in compounds produce their own, but this obviously entails risks.
3, Chop-chop square is very real, and very busy. Particularly on Friday mornings, before prayers.
4, Shopping malls have separate floors for men & women.
5, I visited in November, and the temperature was pleasantly warm in the evening so me & my male colleagues decided to go for a wander around town before dinner. All the cafes were busy with tables of people sitting outside eating drinking, smoking & chatting. All seems perfectly normal for a hot country at first until you realise that the people are all men. Not one woman was anywhere to be seen.
