And it isn't a minority of people. Sure a "minority" in terms of minorities and disadvantaged communities, who actually make up a majority. I know at least half of my city will and is already benefitting- from students who can stay on their parents plan, to women who can get free contraceptive planning, to families who would otherwise watch their children, spouses or whoever die, to families who would otherwise avoid the doctors office until it was a true emergency.
As someone who worked in the hospital for 3 years, and was volutnteering there for 4, I know doctors, nurses, and patients PERSONALLY, and it isn't a bloody minority.
