The ACA has brought relief for 'some' people.The only thing Biden has done is............ Well nothing, really. At least not with anything dealing with healthcare. In fact, he praises the ACA like there's nothing wrong with it.
Bit obviously big insurance companies lobbied and paid politicians to fight against it. Universal, single payer HC never had a chance. And fwiw, it became obvious that Trump didn't have a plan.
We're back to America needing to somehow deal with corrupt government. Your ideas just meet a roadblock if that's not dealt with first.
However, the encouraging aspect of this is that you're at least acknowledging that America's HC is terrible in comparison.
