If you didn't want to discuss constitutional amendments, you shouldn't have brought up something that would require such a herculean effort to make happen that it is not realistic for the foreseeable future and likely wouldn't even get ratified for decades even if somehow you could get that many Republicans and Democrats on board as your example.
Don't be sorry, its all good I'll go to sleep knowing that it's pretty unlikely I'll get shot when out shopping, and if it happens my hospital fees are free. And while away from work, my employer keeps paying my wages because I'm on sick leave, which doesn't impact my holidays balance because PTO and sick leave are separate.
Unfortunately what worked everywhere else in the Western world for a vast amount of issues clearly can't work in the US because reasons. OK.
Sorry... did you think I was defending America? Because I think it's pretty clear I wasn't.
Most of the rest of the Western world is not an oligarchy designed to maximize profits for a tiny handful of people. That is the "because reasons." This is like asking why North Koreans haven't risen up and deposed the Kim family yet. The real world doesn't work that way.
I know you weren't, which is even more frustraring because we want the same things and the only reason I'm engaging :)
Most of the rest of the western countries absolutely are oligarchies designed to maximise profits for a handful of people, some more than others, sometimes a good government happens for a cycle or two and then bad ones for a while. Doesn't mean people can't demand change and sometimes, not always, obtain it.
Many of us have been demanding change for a very long time now. I certainly have. But the people in charge don't want change. I still march for change, but I can't make it happen.
So perhaps consider changing your approach to something that actually might accomplish something? Instead of just asking nicely over and over without results?
