The entire population is forced to submit to every other legislation. I am free to choose my own Dr. The "plan" is everything besides your teeth and electives ar free. You can pay for extras such as private rooms and other various things. 
The only advantage I can see is that you can use money to leverage your position in america, you can buy a higher standard of care... Well why not give everyone the same high standard?

But many countries with free health care they get to have their choice of doctors. So really if set up correctly it's not taking anything away but giving something to many thousands of people who are forced to live without it.

Growing up my dad was a teacher and did not make enough to pay for health coverage for my family so we went without seeing doctors not because we chose to but because we could not afford to.

Australia has tax funded health care for all. It's not what it used to be, but in emergency everyone is equal. 
There are long waits for elective surgery (which seldom feel elective to a long suffering patient) , those with private insurance usually don't wait. Although Australian private health insurance is hugely expensive and always has out of pocket expenses. 
The tax funded Medicare system means that everyone can be admitted to hospital and receive care in acute of emergency situation.

It's insane, Americans have to pay to give birth... Like wtf... You don't have enough expenses with a new child, why not pound a bunch more debt on top while they are at it... It's just a rich man's trick to keep yas all in debt and poor.

If the alternative is paying outrageous inflated prices then yeah I am... look up the cost for a bag of saline in America. .. now ask yourself... how much is water and salt worth really, plus the cost of the bag and disinfection. .. think... then realize it's set up to kill poor people
