ask the japanese how all that overpaying for american real estate worked out for them in the later 1980’s/early 90s and what it did to their own economy.
The difference is the Japanese bought at the peak. The Arabs are trying to catch the falling knife. Perhaps they timed it correct and there will be a bounce and they will make bundles. Perhaps the knife will crash to the floor.
Mind you, the Japanese cheerfully overpaid for all that real estate because their home island was/is so overcrowded. They couldn’t believe how cheap New York was - and they got it wrong.
But I don’t disagree. The Arabs won’t be rich for ever. As long as they don’t get their friends in Congress to force American wells to close, of course.
