New Debtors Prisons?

This article from the Wall Street Journal seems to indicate that people are being sent to jail for failing to pay debts. I practice law in Texas, and I know that in Texas a person can not be jailed for failing to pay a debt. However, people can be jailed for failing to comply with a court order, such as an order to appear in court at a hearing, or to hand over certain documents requested by the creditor. Most states allow garnishment of wages (Texas does not), so I guess in most states you could be jailed for failing to follow a court order to hand over a percentage of your wages. But, to my knowledge, no state allows people to be jailed just for not paying debts. I think there would be a Constitutional problem with that.
