No matter your opinion on the bill, you can't ignore that there are many, many people who now have access to healthcaare who didn't before. whether it was from covering preexisting conditions or expanding Medicaid etc... you may not like how it was implimented but at its core it was absouletely about care.
The affordable part is certainly debatable though.
I chose my words carefully. I said "little" to do with care. Yes, pre-existing conditions was an issue that was addressed. (BTW, one that affected my life greatly).
Not having insurance does not always equate to not having access to care. Talk to our friends in Canada and the UK about the difference between Insurance and Access.
Before ACA, people had access to care, albeit there were some gaps that existed and needed to be addressed. ACA did not address all the gaps and in many cases reduced access to care while increasing people's costs.
One example is a person year who gets sick has to go to the doctor. Assuming they had no insurance, before ACA, they went to the doctor and had to pay out of pocket. After ACA, they had to purchase $2-4K (or more) worth of insurance but still had to pay out of pocket because of the high deductible. Same care except that they likely had less choice because before ACA they went anywhere they wanted to. With ACA, their new insurance company forced them to an in-network provider.
That is just one of a many scenarios.
Add in Medicaid, Medicare, Clinics, ETMALA, and Hill-Burton and people had options for care through those mechanisms.
In short, if you were old or poor, or had a medical trauma, you options for care whether by grant or by government insurance.If you had a job, even if your employer did not pay for all or part of your healthcare, you had options for care.
ACA had some good things but overall let's not kid ourselves about what its intent was. It was a stepping stone to single payer (read: US Government Health Care Insurance.)
It did nothing to address health care Cost.
If you want to debate this topic, start with understanding Payers, Providers, and Patients and go from there.
