One of the major failures of the false impression is that their are people that don't have access to health care. Everyone in this country has access to health care, either through an emergency room, community clinic or other means. The problem with acquiring health care is not access, but personal responsibility to utilize the access to health care that already exists, like prenatal care, annual check-ups, etc.
I don't see the argument that's being made that "only if" people had insurance they would go to the doctor. People don't go now when it's free. What makes them think they will go when they have to pay for it through insurance premiums, or even if they're put on the expanded Medicaid? Some might. Most won't. If they don't now, they wont then.
You can't legislate personal responsibility.
