People have been fighting for those rights for decades. That doesn’t change the fact some people are destitute because of health issues with no way to improve their personal situation. And if I had the physical ability to organise people and fight for things, I’d have the ability to work. I’m not sure you know what ‘100% disabled’ actually means.
Medicare is hugely broken and barely works even for those who are eligible. You still need to get private insurance (called gap insurance) for many, many things.
When I had to switch from BCN to Medicare after I became fully disabled, one of my prescriptions went from $200 a month to $3500, and I started getting denied for routine tests. I was denied a heart cath my cardiologist ordered. I’ve had to stop 4 of my prescriptions because of cost, which of course has made me even more sick.
Even in some utopian daydream, that’s nowhere near ‘universal healthcare’, and expanding that broken system is not a solution.
eta: The US needs actual universal healthcare that’s not inexorably tied to privatisation.
I think society will collapse first, likely due to mass displacement and migration due to climate disasters which will make more people willing to accept fascism.
