The US process is far from ideal. I agree with that. I'm not American and looking from the outside there's a lot of head scratching I can do.
But- It's worked pretty well over the last few hundred years. You can't just take that and throw it in the garbage and replace it with some "workers will decide" socialist mumbo-jumbo.
Seriously. It doesn't work. You can't say let's take Germany's process and apply it in the US. It won't work. We should know better. There is a delicate balance of power (arguably already somewhat disrupted) and there is a culture and a history. That's why we also can't just bring "democracy" to non-democratic countries that easily.
The DSA are saying let's break everything and then figure it out. It won't work. We need responsible adults not revolutionaries to fix things with care.
Isn't it clear to you that you're misrepresenting DSA's position?
Except form the million of black people living in the south of the US. For them, the USA is a democracy only since 1964.
And if you argue "yes but it got better", the Republicans are making everything to get back to before 1964.
Incidentally, your "we can't let workers decide" sounds a lot like "we can't let negroes vote" or "we can't let women vote". And is as much FUD.
I think most of us want a moderate Democrat. I hope populism dies with Trump/MAGA in the coming years. We don’t need to match them with our own distasteful populism.
"Defund the police" was a campaign slogan at last election.
I'm looking from Europe and I'm often impressed how extreme american leftists are. If it's not socialism, it sure shares the same conclusions. And yet "The most extreme left in the US is the most extreme right wing for Europe" is a common belief.
I am often impressed how abusive and violent US policemen are. And they have budgets rivaling the defense spending of whole countries and are armed to the teeth with military grade equipment.
