Money speculators? There’s a ton of them. Look up a list of people who invest in, and then ruined, the Russian ecnomy after the fall of the USSR. Soros and his cronies. They make money off devaluing the currency of nations.
If you’re correct, to me it’s almost like they’re indirectly declaring war on our country. If their goal is a profit with the added consequece of destroying our economy, they should be treated as foreign invaders and dealt with accordingly. :-)
