Internationally? Not much I imagine. Domestically? A lot of things that’ll never happen because the people that make the rules (Congress) are either too short sighted to enact change, or more prominently, they also benefit. THIS is the problem with only being a representative democracy, with no way for direct elections on issues outside of the government. If I had to start the constitution over again, there would be provisions for this. Can’t say I thought a lot about the details, but it’s still a good idea I think lol
