That is utter bullshit. You speak as if healthcare and health insurance were a free-for-all before 2010. It was not. There were no subsidies, no mandate, and a small minority of people weren't covered by insurance. Miraculous but true.
If by small you mean 10-20% of the population, then I guess we agree sorta. That number just doesn't seem all that small to me.
That group can be split between two basic groups. Those who could not afford insurance. For the needy, we had Medicaid. Still do. For those that could afford it but that CHOSE not to buy insurance, the ACA turned the entire process upside down, eliminating affordable a la carte and catastrophic health insurance, forcing hundreds of millions of people to buy unaffordable plans that cover everything including unnecessary coverage like pregnancy for seniors, just so 10 or 20 million can get free or reduced cost insurance.
Because it simply doesn't work. In order for insurance to work, healthy people have to pay for the sick. Before Obamacare lots of people were kicked out of the system for being sick. I have relatives among them. If healthy people don't sign up and the insurance companies want to make any money, that's how it has to be. If everyone who's healthy says "I don't want to pay in unit I get sick", the damn thing doesn't work.
News flash: Obama wasn't the first person to think about how insurance works. It has worked well for decades. Now insurance companies right and left are dropping out of the business. What changed?
News flash, it wasn't working. We spent more for less, I think we still do. That isn't working, its failing. What changed is the ACA was underfunded for the folks needing coverage, they're far more sick than the legislations writers envisioned. It is in need of repair, there is no doubt. But I predict that if the GOP straight up repeals is they'll go form the party of NO to the party of no more. They own it now. If Ryan's Ryan's reverse Robin Hood plan gets passed expect the same results. Folks will get monumentally pissed off when the GOP takes away their health care.
Like I said, I think the GOP should. They should do what they've been saying they'll do. Americans should wake up and realize that elections have consequences, and that's what they voted for.
