no problem, just send a bill for
$45,000 to EACH man, woman and child in the USA, where
$21,000 is the per-capita income...
or
$112,500 bill to each USA household, where
$ 52,000 is the per-household income.
Let’s just hit “clear” and declare a restart. Declare it paid, forgiven, because of all the good things the US has done for other nations. If they don’t like it, we’re sincerely sorry.
