OK, but whoever reimburses your doctor doesn't impact the quality of care your doctor gives you.
A doctor doesn't improve the quality of how they perform their job dependent on the entity that reimburses them after you receive care.
So why does the administration of reimbursements have to be privatized? None of you have been able to say.
You stupidly think this is about jealousy when it's not. It's about you defending something that has no impact on the quality of care your doctor gives you. You doctor doesn't even know who reimburses them after they treat you.
It's jealousy, boy.
I'll let the Constitution explain it. Nowhere does that document give Congress the authority to regulate healthcare or the coverage of healthcare. If you can't understand that, go on begging the government for it.
