I worked for a very ethical lawyer whose specialty was bankruptcy and consumer law. Here's what I noticed:
There are people from all walks of life who feel that bankruptcy is the only solution to their financial troubles. I have dealt with millionaires (who had multi-millions in debt) to single moms who just can't seem to get ahead in their finances. We had one client who was a single mom to an adult special-needs child. She ended up with some emergency medical bills and just couldn't seem to get them paid off. We also had a few clients who were up to their neck in student loans. (Note: it was my experience that student loans are not dischargeable in bankruptcy. They must be paid off.)
There are lots of people who are declaring bankruptcy lately. They lived beyond their means when the economy was great, then had to pay their debts and couldn't. Bankruptcy law runs counter-cyclical to the rest of the economy--that is, when the economy is great, bankruptcy attorneys don't have a thriving practice. When the economy takes a downturn, they have more clients than they know how to help.
It is my personal opinion (take that for what it's worth) that bankruptcy should be a last resort. I think that it is unethical to declare bankruptcy in most cases, except those where sudden tragedy strikes an otherwise responsible person who genuinely makes efforts to pay his debts. (Medical emergencies or loss of child support, for example.) That is just my opinion, from what I observed working for the bankruptcy attorney.
There have been several changes in bankruptcy law over the last few years to make filing for bankruptcy stricter. From what I saw, they were good changes and helped to keep people from taking advantage of bankruptcy discharges.
