Medicare for all is something I 100% support.
Yet I respect the opinion (or fear rather...) of Americans who have more pressing concerns. More important than even their own health, or that of their families. See, they're not entirely stupid. They know it'll cost a mighty penny to pay for this.
My view is that, by starting with asking people to "pay" for Healthcare, you've scared them off. It is putting the cart before the horse. We need people feeling secure in both food and housing before we extend our reach beyond absolute, immediate, necessities. The entire fight against the ACA was that the American people, too many of them, think they don't need to pay for Healthcare. That the market will provide, or some similar BS. They will not understand the tax for it, as much as they'll understand the tax to pay for food and shelter.
Instead of starting the conversation with such a difficult subject, I believe it is our more pressing concern to talk about the Safety Net from the ground up. Basic Income and a Housing Loan Program. Those have huge, immediate, return on investments. People understand getting $1,000/mo. They understand NEVER being foreclosed on, and never missing a house payment. Never being homeless for financial reasons. They'd eventually understand the great bounty that is the $216,000 nest egg EACH child receives at 18. These are huge, life altering programs to directly benefit our people.
Healthcare is similar, but once you do all these things you're looking at a total tax rate between 40-50%. People cannot comprehend that being a good deal for them today. We need to prioritize and get the ball rolling with parts we need the most, that directly benefit them the most. Then convince people that a similar benefit awaits them for other programs, like Medicare.
As for Education, that needs to be revolutionized to cost a fraction of what it does today. For most fields we can achieve cost effective solutions, and then we'll see what remains in the budget to assist in paying for it. Our workforce needs to be healthy and educated, and these things are not mutually exclusive, but I think we need to tread carefully with respect to what we ask people to pay for, before we demonstrate the benefits to them.
We need to understand that these programs are not cheap, our people already know and fear that. We need to demonstrate the benefits.
