Someone who uses all their money to make a business and chooses not to buy health insurance to save money is taking a calculated risk. That's on them. I say that's stupid, but that's a matter of opinion. Should the government force that person to pay for health insurance even though it would mean they could no longer afford their business? I think that should be the individual's choice, not government's mandate.
It's on them, and everyone else who has to pay their emergency room bill when that's the only recourse after they've been unable to afford preventative care.
The government does not force businesses with under fifty employees to provide health care.
