I refuse to accept the view that mankind is so tragically bound to the starless midnight of racism and war that the bright daybreak of peace and brotherhood can never become a reality. - MLK
I think the concern about the ACA has been misstated. It's not that not enough people would sign up, it's that not enough of the right people would sign up. The right people are those who are any combination of young, healthy, and able to pay an above-value price for their insurance. Don't get me wrong, the administration set up this 7 million mark knowing they'd meet it and give good publicity to the program. The true test will be in the demographics that signed up (which I believe is impossible to know right now).
