This whole scene shows the "tragic flaw" of the nation-state system: "Nations" have made a virtue of necessity by pretending that "diversity" is an asset, as they grow by conquest and accident. In the meantime, the sort of family spirit of ethnic identity, however flawed, is drained away. We're left with a rational response by the Rich: feather your "own" nest, which means , don't impoverish yourself and your family by making investments in the US, when you could make more money by gaming the system, elsewhere. I can remember when it was considered a disgrace for a "CEO " to lay anyone off; I believe my own grandfather ran afoul of this during the Depression. Bankruptcy was the result.
The fact is, National Sovereignty is a lethal metastable condition in the modern world, so the decline of nation-states is a healthy development. There is simply no way this setup can lead to anywhere but conflict and war, since there is no legal structure to settle disputes.
That Japanese classic "the 47 Ronin" shows the folly of trying to make an unstable system work. (It was magnificent: a dedicated group of super honorable men , who at great cost to themselves, tried to make the Feudal System work).
No matter what the Rich buy, they are not going to be able to save our "Nation". (I call it that from habit, actually the US is a polyglot empire, like Austria-Hungary) disigny
