I disagree.
Why is that? It was a resolution proposed to congress by the republican senate leader, and not one person voted for it, not even him. If one supports something and then offered to have it, but in such an unrealistic extreme to be impossible to support, it's easy to say they don't really want or support it. It was intended to be divisive to the democratic party. It was in fact a stunt, recognized as such, and all the present votes were a unified protest vote.
It's the only idea that actually attempts to address the problems you have. The numbers mean that the country isn't ready for it, just as MoSW says, but the fact remains that there are no competing proposals. They voted down
Climate change is real. I admire AOC for trying to do something about the problem instead of spending her time bitching about her opponents.
She does have a dream, but it's an immature daydream which has opened herself, her party, and the entire cause of combatting global warming to mockery. If nothing else, the democratic party has a lot of pressure now to do better than her.
The way I see it, if even small parts of that dream are implemented, we're all better off. The alternative is - wait, there is none. *Nobody's* come up with anything, unless you count the Trump administration wanting to drill for oil in areas banned by the Obama administration.
It's drastic, sure, but not immature. If anything, it's far more mature than the spite from her opponents because it tries to solve the problem rather than ignore it.
