The skyscrapers in the desert mean absolutely shit, though. Likewise man made islands that disappear without constant care. Those are not investments.

Using money to make more advanced development possible, that's investments. The Norwegians got it right IMHO - they put all their oil money back in the economy, and they are punching now way above their weight! They have about 1% of the EU population, but own about 10% of EU Companies through their investments. Bar any major catastrophe, or very stupid decisions, they will have a good life for generations to come, regardless of their oil futures.

I don't think it's beyond the realms of possibility to imagine future generations might look dimly on wealth gained from oil.

In the a similar way as current generations look dimly on wealth gained by stealing land from indigenous populations, or on wealth gained from cutting down almost all old growth forest, I presume.

People who are well fed, clothed, properly housed, and with little to spend their time on often criticize the culture that feeds them.

Those that aren’t don’t criticize their culture? Seems like maybe criticism is a constant.

I'm pointing out that people who are very well off tend to criticize the culture that provides them with the comforts of modern life while being oblivious about the benefits of their culture which they enjoy. I made no claim about other kinds of people.

Agreed. The Saudis have been snatching up real-estate all over Europe, America, and the middle-east. KSR is the largest foreign investor in Turkish real estate. If you remember the Gezi park protests, they were more about Saudis and Qataris forcing unwanted conservatism on the Beyoğlu city of central Istanbul than it was about saving the park.

The average Türk, except for the very upper-class, would be very happy to end the influence of the Saudis in their country.
