With a Jan. 31 deadline for the uninsured to buy health care coverage, the challenge of finding affordable premiums has the potential to derail Obamacare, Professor Robert Field said on an interview aired by NBC 10 on Jan. 28.

“One of the premises of Obamacare is that we’re going to be active consumers, that we’re not just going to walk into the Best Buy and say ‘What TV should I buy’ and walk out with the TV,” said Field, the author of “Mother of Invention: How the Government Created ‘Free-Market’ Health Care.”

The segment featured a one-on-one interview with President Obama, who cited low premium rates for most consumers.  But NBC10 also interviewed a Philadelphia woman who said affordable monthly premiums of $75 carry $6,000 annual deductibles.

An authority on health care policy and health law, Field frequently writes about the Affordable Care Act in The Philadelphia Inquirer’s "Health Cents" blog.
