More than 40 percent of Americans making between $20,000 and $40,000 a year live without an insurance. Hard to believe? Well, read on.

Sara Collins, Commonwealth Fund senior program officer says:

20 percent of working adults are paying off medical debt - often $2,000 or more and 60 percent of uninsured adults with chronic illnesses such as heart disease skip pills to save money.
… the 40 percent figure is a dramatic and rapid increase from 2001, when only 28 percent of the people in this moderate income bracket were uninsured. The jump in uninsured among those with modest incomes is alarming, particularly at a time when our economy has been improving.
If we don't act soon to expand coverage to the uninsured, the health of the U.S. population, the productivity of our workforce, and our economy are at risk. For an uninsured person, who is unlucky enough to get sick, it is easy to see how quickly they can fall into a downward spiral of debt, forgone care, and poorer health…

I think the concern of the government is a step forward and if it is actually able to work on this, then definitely they will be able to eliminate the risk of low productivity. This because their workforce would have better medical conditions.

And if the productivity is not low then the economy would improve rather than being at a risk.
