Obama tax plan
So, I'm in support of income re-distribution and progressive taxation. But I finally took a careful look at Obama's tax plan (after a friend pointed some things out to me) and I see some things that I'm not so sure about. What is the economic rationale for "refundable" tax credits? I'd be happy with his tax plan (http://www.barackobama.com/pdf/taxes/Factsheet_Tax_Plan_FINAL.pdf) if he'd just remove the word "refundable" from it.
