We have had progressives in congress trying to expand on that for generations now, they have not been able to do so, they cannot get enough votes to pass those measures, so how can we expand it when we cannot even manage to fix it?Yes, by expanding medicare to cover all medical costs and prescriptions. That's the big hole in medicare and having such a massive base of people with which to negotiate prescription drug prices instead of dozens of small companies with basically no government bargaining is an instant fix in that regard.
But Biden is very specifically against solutions like this and very much pro putting people into debt for his industry friends, so no to Biden. He can't be helpful.
Though it should be pointed out that no healthcare system in the world actually covers " ALL" medical costs, as "ALL" medical procedures are not even considered reasonable or necessary and thus why we have to determine what is and is not reasonable or necessary otherwise there is no way we could actually afford to maintain such a healthcare system. What we can and cannot afford is what is being debated, and republicans have unanimously determined that we cannot afford even our current costs and are actively trying to reduce them, thus why we cannot manage to get even the smallest expansions approved in a conservative heavy congress. The ONLY way we have been able to get medicare and medicaid expansions passed in the past have been through managing to get some conservatives on board as well, which has proven to be extremely difficult and involve heavy bribes. In the current partisan environment however, that is a near impossible task as any Republican that has supported such measures is often run out of office by their own party.
The BIGGEST difference between the two parties is there is only ONE party that has progressives or progressive agendas in it at all.
