When looking at this just a little further....

From the article...

The vast majority of households making up to $30,000 fall into the category, as do nearly half of all households making between $30,000 and $40,000.

As you move up the income scale the percentages drop.

Nearly 22% of those making between $50,000 and $75,000 end up with no federal income tax liability or negative liability as do 9% of households with incomes between $75,000 and $100,000.

I couldn't even think of trying to make it on $30,000 - 40,000 per year. And these numbers could be for a family. These people are at the poverty level.

But my father always used to say:

You can't get blood out of a stone.....
