One expert said 'the govt will give us details later, but expect a smaller refund on your taxes'(sic!). If you are not "poor" I suspect you will get a high co-pay on med bills since USA health is super-expensive and our govt is bankrupt.
My only idea of what I might copay, is from high deductible health insurance policies. The premiums are higher than the proposed non-insured 'tax' penalty. There seems no guarantee in Obamacare that you still won't have to dip into your saving and nothing is clear about what coverage you get, for what.
