The consequences of SCOTUS awarding this case to Trump would be catastrophic, far beyond one person's job. Long-term interest rates would spike, the purchasing power of the dollar, crash. Financially, the US would join the Third World. ("Shithole countries.") Trump has openly mused that...
...devaluing the dollar would be good, a way to lessen the burden of the National Debt and increase exports. He's an idiot. What are we going to pay it down with, if our dollar is worth less? And when American companies shutter under internal financial pressure, what will we have to export?
Yes, this is a big one.
