As everywhere on lemmy it will be "oh no, only the rich will get it".

Yes, as with every new treatment. But also, once it's ironed out, it will become available to everyone.

No, communism won't solve the scarcity problem of a newly developed treatment, although it would imply a different distribution mechanism. And if socialist/communist society isn't a perfect utopia you somehow imagine we could transition to tomorrow, you'd see a distribution mechanism for those novel treatments to be unfair in other ways.

So, here's what we have: money is being invested into novel treatment research, it's initially only affordable to the rich, then to those who're willing to sell their house for it, then to those with a private insurance, and then, eventually, to everyone.

It's not a perfect system, but it's a system that gets us all better healthcare every year.

So, ask yourself if maybe every one one of your comments always boils down to "I wish we lived in a communist utopia". Cuz, you know, I'm actually with you, but I don't see this running in circles being useful. And, for your default country, I also hardly see a way there through a democratic process.
