If you are arguing against a $450 medical procedure, you are living in a fantasy world!
I wish I could find medical insurance for less than $450 per month. Insurance I will hopefully never need because I'll never meet the $5000 deductible. And dental isn't even covered! I would welcome a mere $450 dental surgery bill. From my experience an actual dental surgery bill runs in the $thousands.
I am a healthy American who takes care of himself. Why should I be forced to pay for the un-insurable by paying outrageous premiums for what amounts to catastrophic only insurance? I would be much better off setting that $8-900 per month aside and self insuring myself.
Technically you previously would have paid for the uninsured anyway, through taxpayer funded reimbursements for Hospital Emergency rooms and also generalized inflation spread across the entirety of the system. Making this much worse is that care given is the most expensive and the last effective. It would be far cheaper to give them the needed medications and preventative care up front then waiting until it is an Emergency room situation and spending far more to achieve far less.
Now that said, I do think there are better ways to go about doing this and the whole of healthcare then Obamacare, ones with far fewer mandates, which also raise costs.
