It's all part of the agenda of Obama's socialist regime to have a one payer system. It doesn't work for the people but you can't teach a libertard jack.
Even a single-payer system will not work any better if doctors switch to a cash only practice and leave it to the patient to file for the partial re-imbursement under the new law. That way the doctor gets his price it takes to make a profit and will leave it to the patient to eat the loss. Like they say, there is always more than one way to skin the welfare cat.
As for the buying of goods from those going broke, I am finding a lot of good deals now. Craigslist has been a good source to turn that stuff into a healthy cash profit. Did I mention it is completely tax free profit. All sales are for cash only and it has been great both in buying and selling.
And you are correct, anyone that files a tax return will be required to buy health insurance under current law.
