Christmas 1971, when I was working in Pittsburgh, my mother died in Britain. I felt I must attend the funeral even though it meant spending money I'd saved to cover any emergency that might happen to a foreigner (with a wife and two children) working in the USA.
But to leave the USA I needed clearance from the Internal Revenue as proof I'd paid my taxes, and the IR office was closed. Ed, the father of one my daughter's friends, was an attorney; he phoned me, "Call your congressman." I pointed out I was a voteless alien. Ed said, "Call him and tell him I'll call him if he doesn't do something. And if you're short of cash I'll let you have anything you need."
As it happened things went smoothly. I was reminded of this when the new president ended his speech exhorting Americans to think only of themselves.
