Wealth can be a mixed blessing...
the worlds bankrupt Lottery winners prove that better than anything I know of.
No kidding!
When my husband and I lived and worked in Saudi Arabia we were, to us, WEALTHY.
The American and Saudi governments have a DEAL going so WE Americans pay NO FEDERAL INCOME TAX on Saudi earnings. We were able to travel ALL OVER THE WORLD, buy a home in San Francisco (second year there) and had it PAID OFF completely, IN FULL, after only nine years. We had more money than God.
Also, since we were out of the Golden State for longer than a year we ceased to be residents there and paid NO STATE INCOME TAX. We were rolling in dough.
Some ARAMCONS stay there in the KSA for their entire working life. The Saudis don't let them become citizens but they can stay until they retire. Mandatory retirement is 60 years of age.
We stayed there for only five years. Enough was enough. It was TIME TO COME HOME! I KISSED the ground of the USA at our first port of entry (LAX).
