At least according the NPR article you posted, 38% is the number when there are not large stimulus-related tax breaks:
It doesn't appear that there will be deficit busting stimulus legislation like this for a long time to come.
From your NPR article:
"In 2008, President Bush's stimulus payments sent $600 to individuals, $1,200 to couples, plus a little bit more if you had kids, and that all showed up as a tax reduction when you filed your income taxes.
This year we have the 2009 stimulus, which includes making work pay. Almost every American who works got benefit from that and a few other things that bring down tax bills."
As you quoted, it's mostly low income families. More detail is here:

http://blogs.ajc.com/jay-bookman-blog/2009/02/24/the-50-percent-pay-no-tax-fraud-part-ii/“Broadly speaking, the 44 million zero-tax filers are: low-income, young, female-headed households, part-time workers, and beneficiaries of the $1,000 per-child tax credit.
The 44 million zero-tax filers will be largely low-income. Indeed, 75 percent of will earn less than $20,000 per year and 97 percent will earn less than $40,000. Fewer than 1 percent will earn more than $75,000 per year – a group comprised largely of business owners whose tax liabilities will be erased due to business losses, carry-overs from prior year AMT payments, or foreign tax credits."
so 97% are low-income families that earn less than 40,000 (not 50,000). If they have no kids and are not disabled, they would pay at taxes on $40,000 no problem....
And who is responsible for them not paying taxes? The compassionate conservative himself GW Bush:
". First of all, as the Tax Foundation points out, the relatively large percentage of non-income-tax payers is a direct consequence of the Bush tax cuts that conservatives laud in other contexts. As the foundation pointed out in 2004, the number of zero-tax filers “was 29 million in 2000, and it will be 44 million in 2004, a 50 percent increase.” Again, it attributes that change to the Bush administration."
So the conservatives have created a situation where the poorest do not pay taxes, which they can then point out is not fair. Interesting isn't it?
So your entire argument is highly misleading, although technically you state the "facts."
