If you ask this question again after I've already answered it, you will show yourself to be a dishonest actor, asking dishonest questions
Sanders bill requires everybody to opt into it because if only the poor people who needed access to healthcare opted into it, there is no way it would be able to be funded
Do you understand that part?
All the poor people without healthcare opt into it, but there is no way for them to pay for it
So, in order to pay for the healthcare all the poor people need, rich people have to also opt into the program
Still with me?
Rich people can already pay for all the healthcare they and the members of their family need, there is no incentive for them to pay more in taxes to provide the healthcare poor people and their families need. A law is required that says that if you're rich enough, you also need to pay a small premium so that poor families can have equal access to the same kind of quality healthcare they have access to
Thus providing quality healthcare to poor people who cannot afford it by no fault of their own, ensuring 30 million + more Americans have access to affordable healthcare, and ensuring 45K fewer Americans die every single year because they don't have access to adequate, affordable healthcare.
Ask that stupid question again, Idiot.
