Absolutely. The US has shown it is happy to threaten allies and weaponise everything it can in international relations. It would be madness to leave critical payments infrastructure dependent on the US.

Considering the times we're living in, each country should consider implementing own payment system, and never abandoning cash for digital currency. Both systems should coexist and complement each other but we aren't living in a perfect world.

The US has a long tradition of arm-twisting to forward its business interests.

This habit is starting to do more harm than good (to them) and they should try to focus on innovating the way China does.

I think you mean this habit has benefit no one outside of a small elite moneyed interests that want to protect their fief.

US foreign policy does not benefit Americans, it benefits the elites.

Absolutely. Look at the Portuguese Empire: even at the end most Portuguese were poor and many had to emigrate.

Most British had a low standard of living going into the XX century. Engels' report to Parliament painted a bleak picture of the standard of living in Britain at the peak of the British Empire.

Yup

Americans will be "pro free market" until it's somebody else doing the competition, then they will be very butthurt about it (at best)
