Just not true. ACA is NOT a UHC plan and we absolutely don't NEED single payer. Granted, single-payer works. BUT as a delivery mechansim for single-pricing so does multi-payer [see Germany]. Ultimately, no one really cares how many payers there are. What's CRITICAL is UHC. hc4.us/oneprice
Can you point out who, under the original ACA with its mandates and expansions in place, would not have had healthcare coverage in the US? As it was written and before they spent nearly two decades gutting it of course, as now it's garbage without any real merits outside of a few provisions.
ACA just another commercial tier. Even w/ all those who are uninsured added (somehow) to ACA coverage it would not be the same as true UHC - which is the delivery mechanism for SINGLE pricing. Tiered coverage is the delivery mechanism for tiered (and uncapped) pricing. THAT'S the systemic flaw.
My surgery shouldn't be 2.5X the cost (Nat'l avg) my neighbors - simply b/c we're in different coverage tiers. That's the insanity - and ACA doesn't fix that. It just extends coverage into the systemic flaw of tiered pricing.
