Wow, you are really going to argue the ACA isn't healthcare reform just because it's not single payer? It is insurance reform, but also contains the largest expansion of Medicaid since the program was created. But let's look at some of those horrible neolib reforms that you think insurance companies wanted so badly. Well, they can't charge a soon-to-be retiree more than 3 times what they charge a healthy 25 year old for the same policy. Insurers and Republicans, on their best day, wanted a 5:1 ratio. Insurers are capped by the 80/20 rule in terms of what they can use your premium for--80% has to go to care or they refund you. Insurers cannot discriminate against people with preexisting conditions, cannot drop coverage once paid, cannot cap coverage (lifetime caps), and have to offer consistent policies in a given market. The law includes premium subsidies for exchange market purchasers beneath certain income levels, small business health insurance tax credits, and employers of certain sizes are required to provide coverage (and it has to meet quality-of-care standards). There's the quality-of-care reforms, closing of the prescription drug donut hole, and end of life services now in Medicare too. Oh, and it increased funding for a whole bunch existing programs. That's not all, but a decent roundup.
It's hard to read progressives make ill-informed statements. ACA isn't all it could be, but a few changes like increasing the premium subsidy levels, prescription drug price ratios, and red states expanding Medicaid and you have a pretty solid system. You can make a crappy single player plan, after all, or get an NHS that's underfunded like it is under the current conservative regime in Britain. There's no guarantee one will work as well as another (although I'd personally like to see some form of single payer).
