Obamacare should have been a single-provider healthcare. Thanks to Republican governors insisting that their states use the federal exchange, we're already half-way there to single-provider healthcare.
Great! Instead of a pacemaker for a cardiac issue we can then just "give Grandma a pill" to ease the pain while nature takes it's course. Too bad about Grandma but it saves the Collective money, right?
You people have no clue what you're letting yourselves in for in the near future. You think the government is corrupt and over-reaching now? Ha! Once more of the ACA schedule is enacted you're going to have political/ideological enemies, journalists, and critics suddenly and mysteriously have trouble getting health coverage for random procedures, etc, and mysterious and life-threatening mistakes to their personal electronic health records, and sudden IRS trouble related to mandatory coverage as well.
There are few more intrusive, personal, and powerful tools of control over people than to control their access to doctors and medicine. That's why ACA was passed despite ~70% of US citizens opposing it, and don't even try to say otherwise, those refutations have all been debunked. "We have to pass the bill to see what's IN the bill." is a pretty stark admission of how much the public opposed the ACA when they weren't even willing to let anyone see it until they passed it.
Me? Screw the ACA! I'll go outside the US for healthcare.
