This blog has interesting and depressing statistics about health care debt for our country. The main site also has some good information on credit cards, which are good, which are not, and how to think about using them. Of course most of us do not have the luxury of deciding which credit cards to use, and low-income people are often left with only the worse options (high interest, poor terms, etc.) However, now that we have the Medicaid Buy-In option and more of us are able to get and keep jobs, as we get out of poverty we can learn about things like credit card choices.
Anyway, the health care debt issue is something important.
