So what would you do if your mom or dad, or perhaps your sister or brother, needed a kidney donation and you were the one best positioned to donate?

Most of us would worry a little and then step forward. But not so fast. Because of our dysfunctional health insurance system, a disgrace that nearly half of all members of Congress seem determined to cling to, stepping up to save a loved one can ruin your own chance of ever getting health insurance.

That wrenching trade-off is another reminder of the moral bankruptcy of our existing insurance system. It’s one more reason to pass robust reform this year.

Over the last week I’ve been speaking to David Waddington, a 58-year-old wine retailer in Dallas, along with his wife and two sons. I’d love to know what the opponents of health reform think families like this should do.
