Singularly the best resource on The Affordable Care Act published to date
This article is lengthy, but it should be a required read for every American of voting age. It goes into the history of the American medical system, the rise of Medicare, Liberal's past attempts at universal healthcare, the logic behind the "individual mandate" and the historical references to why this could work.
It is not a partisan pontification of why the ACA ("Obamacare") is fantastic and is going to change our history, and it is not a slam against ACA opposition. It is an unbias approach to explaining why health insurance reform is required in America while addressing the concerns of its opposition.
You're going to spend twenty minutes reading this and another hour going through and clicking on all of the sources contained in this article. This article is very well cited with sources coming from reputable leaders in their fields, like the Wall Street Journal.
This, my fellow Americans, is what the Affordable Care Act is - without the spin.
