Yes, the disparity is the problem. But it needs to actually be spread out. Things like universal health care do that inherently if they properly raise taxes on the rich.
Redistributing wealth from the top 0.1% to the top 1% doesn't accomplish anything meaningful.
And yes, paying for it will come from taxing the rich. None of that has to do with capitalism exclusively.
I feel like we're after the same thing but you're more interested in attacking my idea than building something together or proposing something different. I'm sorry if that's harsh, but your questions are quite loaded and you didn't offer anything of substance yourself. The only thing you didn't deflect back to me was saying "the disparity is the problem", and that is precisely the point I was making. I'm specifically pointing out that it's about the full disparity.
