Just my own humble opinion, but it would be nice if maybe someday we have a revolution and in the result of that revolution everyone has to be interviewed. Those who are found to be Americans, who are productive, who speak English, and who contribute in some way to the country (even if it’s just by their example as individualists) will be welcome to stay and will receive citizenship in the new republic.
The other types, for whom English is and always will be a second language, and who cannot fathom the idea of supporting themselves, and who think that other people should support them, and who think that stealing wealth from others is the path to happiness...all of these people will be sent to the Mexican border, airdropped on Syria, or anywhere else stupid enough or anarchic enough to take them.
Those who remain, be they white, black, or etc. will be Americans and they will build the new Republic whose Constitution will not be a mere suggestion, but will be the law.
Other countries would have to be paid to take them. Trillions maybe. But it would be worth it.
