Under your argument why don't we try and end public schools, medicaid, ss, post office since those things will just be sabotaged too?
The public school system is exactly the sort of disaster we'd be trying to avoid as we move towards building a great healthcare system. Public schools are an imperative, because everyone
must achieve a minimum level of education to even begin to function in society. Within the healthcare system, we afford this "minimum" to people by providing free care when necessary and with programs such as medicaid. Meanwhile, we require that businesses and self-employed entrepreneurs support the system with insurance plans that actually pay enough to actually keep hospitals open (private insurance indirectly subsidizes medicaid, and that's indisputable). It's also indisputable that public schools perform atrociously in America, a product of American culture and politics. Healthcare would suffer a similar fate without proper political changes first.
A fundamental difference between medical care and schooling is that educational inequality is perhaps the
primary driver of socioeconomic inequality. Educating one person and not another creates an unjust society. Meanwhile, good healthcare for anyone is objectively a good thing. While some would rather see two people die of cancer than see one survive and another die, those of us living in the real world know that all (proper) healthcare is good healthcare. I life saved is a good thing. Don't dismantle the parts that work and replace them with a universally poorly funded less accessible system. Instead, increase subsidies and work on private insurance reform to make healthcare more affordable and less predatory.
The post office acts more like a public service for people who live outside of the usual delivery areas for shipping companies that typically do a much better job meeting deadlines. It is important to maintain as a safety net for remote areas, but not something that should be expanded to all our shipping and receiving needs.
I would suggest passing medicare for all by any means necessary, regardless of how close it is.
Then I think you're foolish. We need changes that will
work, and we need to slowly build to a better system that fits the will of the people and those they choose to represent them. The best way to fail to delivery affordable, universal healthcare for decades is to force it and fail. M4A already has many flaws, and for it to pass it will be bastardized a hundred times over, creating a monstrosity that will be doomed to fail, much like Green Mountain Care in Vermont.
Not only will it leave an incredible human toll, but it will create the narrative that single payer doesn't work in America. Frankly, I think that narrative is correct, I just think it's for the opposite reasons that the Republicans cite. We must drastically change politics if we want to be successful drastically changing healthcare, and until then we need to pass the reforms that will be successful, like private insurance reform, increased subsidies, etc...
