Who's angry about how people are spending their already-taxed income? Is that really a thing? Is it sincere or just racism masked as "think of the economy"? (Honest question, Not American. Don't live there, news to me).
The big beautiful bill included a 1% foreign remittance tax for outbound international transfers funded using physical cash, money orders, and cashier's checks.
Which notably, doesn’t affect money transfers in general, just ways that poor people transfer money, so the concern as stated is not in good faith at all, but rather a way to further punish migrant workers, primarily Mexicans, and is absolutely racial animosity.
