Most people are good with the system. Can't please everyone ever. As for why we have it, it's an inevitable result of our Constitution.
https://en.wikipedia.org/wiki/Duverger's_law If we changed it, we'd end up having coalitions formed that more or less matched up with the current system, with some other changes that I think a lot of advocates for changing the system would not like. I'd be open to discussing it (that is, to potentially supporting a change), but it's a lot more complicated than I think people appreciate (that should basically be my sig--ha).
That Duverger's Law read (looked it up more last night as well) was very insightful. I'll have to think deeper about my suggested change, as I agree it may be more complex than I gave it credit for. I think there would have to be a new process that has evolved from what we've learned if we took that route, but if it's too experimental to risk if it's too different, and the original proposition seems that it may cause a few unintended consequences.
As you describe it, maybe? But basically our system is designed to change slowly, and only in line with changes in public opinion. Look at the ACA. We passed a big overhaul of the healthcare system that expands access to gov't-provided coverage, creates a means for people shut out to get access to coverage (and provides for subsidies to help them pay for it if they can't afford it), increases regulations leading to more people getting coverage from work or through their parents, and pays for it all with higher taxes on the rich. That was hugely controversial and faced massive lobbying and united Republican opposition. But then when they regained control of the gov't, the changes were mostly too popular to reverse, and it looks like it'll stick. Democrats are now trying to expand even further, while Republicans still dream of rolling it back, but it's looking increasingly politically toxic for them to do so. That's how we get change, I think. Once in a while, a party is in position to do something big, and if they do and it works, it's hard to undo, and it gets expanded on (see also SS, Medicare, Medicaid, SNAP, and more).
Good points, but one of the biggest flaws I find with the two party system is the opposition to obvious benefits for society. In your ACA example, the Republicans went to oppose it (a plan that as you explained came with massive benefits for society mind you), with literally no plan at all as an improvement alternative. I'm fine with listening to an argument why an alternative plan is better, even if I don't fully agree, but on paper it looks like they wanted to remove it for the sole reason that "Obama was involved". That isn't policy making, it's a direct result of the two party system with Republicans not wanting to give the "win" to Democrats with the ACA. Fortunately it gained enough traction that it wasn't replaced with a literal donut, but that's the power of counter productivity the two party system can produce. I'm not sure how it could be done after reading up some more on government history's, but I'd be all in on some sort of regulation or control that combats obvious measures that are taken against America's interests such as this.
The problem is that to set policy, you need the cooperation of a huge number of people in gov't. So really, the letter by the name is the most important thing. For that to change, the pattern of elected leaders' actions would have to change. You can have a really intelligent, decent, experienced candidate but if he's in X party and you oppose X party's agenda, he's not the guy you want because he can be expected to fight for X's agenda. The letter is effectively a pledge.
I will admit I've changed this stance here after reading up. The alternative looks worse, as I'm not a fan of having "38 coalitions that lead to a couple with the most power, while the 36 others form alliances with those two". You were dead on when you said our current system is an evolution of the system itself. I still feel we can continue to evolve it, but I'm not sure at the moment how without risking a worse scenario.
I think it would be good if he didn't have a seat, but the people of Florida disagree. He's going to reliably vote for whatever Republicans want so if that's what you want, he's the guy. That said, note that the GOP's *policy* agenda is largely unpopular with its own voters. In fact, accurately describing it (for example, saying that the Trump tax cuts were tax cuts for the wealthy and for corporations) is often taken as a slur. But for Republican voters, it's more about repudiating popular culture and obnoxious college students than setting policy, and the policy agenda fits a narrative that is consistent with that.
This of everything sums up what I find the biggest problem of all, and this one is peak two party. You have Rick Scott, an abomination of a human, who has dedicated his life into lies, corruption, stealing from the poor, bribing, etc. This isn't CT, it's actually already proven and documented. Double that down with nothing that he was actually proposing to do was beneficial to anyone except a select few. What do you get? Rick wins the Senate seat. Why? Because can't let the D win so vote R. People are willingly and quite literally throwing away their interests to vote for the letter R in this case, caring not about anything else. I know an argument can be made in the ways of "technically he was fairly voted in by the people", which I can't argue since that is definitive democracy, but would there be any other scenario that he would have won without this system? I'd say an outstanding no. That party line vote outweighs the policy or character vote too often, which is my #1 problem with the system currently.
I think that the deeper problem is this one-two combination:
1. The "liberal media" CT
2. The existence of an alternate-reality media sphere.
The GOP can basically get away with any level of corruption and maladminstration because half the country simply will not believe any stories about it, and they will believe media outlets that will lie about it. That's not a problem with our governance system; it's a problem with our information environment. I think it's like blaming the cook if all you have to eat is shit. The cook is going to do his best and he might be good at his job, but fixing that problem is beyond his capacity.
I agree with the information part for sure. I believe almost all tv media/tv news is trash now, which feeds the issues. When you read the articles from websites, even Fox sometimes, they tend to be pretty solid. Information is so accessible you can simply subscribe to AP and Bloomberg and get alerts on your preferred reading. But most people turn on their tv or social media and get junk versions or emotionally charged versions of the news. Then when they are fed this, you'll get some radical takes like "did you see those stats, Obama taxed more poor people than anyone, MAGA 2020" or "did you see those stats, every politician in history is corrupt, except Bernie". Those are actually real life examples I've discussed with people. It removes a level of discourse because now instead of discussing the context of viability, you're discussing if they are accurate in their assessment. That is, fully, fully, fully powered by the media, social media, and disinformation. True, that it may be impossible to fix at this stage though.
