First things first: belated best wishes and prayers for Wildartist and Bushrat.
Second, re: reserve currencies — being “the best looking horse in the glue factory” does little for longevity. Enough has been written about the many ways in which the USA is wide open to be ruined, both by supporters of, and detractors from, the nation itself, and its dishonest monetary unit ($FRN), that the whole world now has an online compendium of strategies — financial, social, political, and military — to collapse us (not that anyone would actually try … right, Barry?) My guess is that multiple such strategies, both foreign and domestic, are already in progress. If the fedgov interrupts any of them, it is probably only to control the timing so maximal damage will result.
