True, it's just a voting system. It can't do those things unless people vote for those things to happen.
The thing RCV does do is break us out of the control of a 2-party government. So we could have a communist party with RCV, but can't in our current system.
I think our opinions on the law are irrelevant here. The SOCTUS said it's lawful for the president to impose tariffs. So the only way to change the SOCTUS decision is to pass another law making it explicit that the president doesn't have these powers.
I'm not a lawyer so I can't interpret the law. However, the judicial branch can and there haven't been any rulings which have indicated that the president didn't have the power to set tariffs.
Another law would be needed to be passed so judicial rulings could say the president didn't have this power.
China has the edge, here. Its communist single-party system and centralized planning allow them to quickly adapt. The US, as a democracy, moves slower making it harder to change. I think China knows this, and they’re betting the U.S. will cave first.
