How is that good?
I'm willing to pay for myself but not for others.
That's socialism and I don't want that.

Or, are you saying that we're not paying for uninsured people but instead that since most everyone has coverage, the pool of people is larger and that's the 'other' in your statement? Because if that's the case, than that's OK -- no different than other insurance programs (house, car).
Still, healthy people should pay less, just like safer drivers pay less.
