Half our registered voters don't even want to pay for healthcare for our citizens, why do you think we would pay for this?
I haven't met many fellow Americans who are willing to pay for healthcare for anyone. Half of them are willing to subsidize private health insurance, which is still a right-wing approach seen from a world perspective.
It seems like another way to move money from the middle class to corporations, giving the lower income workers extra expenses they can ill afford, even subsidized. It doesn't help to have health insurance if you cannot afford the co-pay and OOP expenses.
The very idea of funding healthcare directly, not going through private insurance intermediates who milk the maximum amount of money from both sides, is one that seems alien to Americans, no matter what party they claim to support.
