The article doesn't state enough information to judge all of their decision making. I'm sure most of us would have been more conservative.
However, I think the message in the article is that you can seamingly do everything right (education, work history, well paying job, etc..) but in this job market be sent back to square one. A person can have a $200K education, $100K of continuing education, 25 to 30 years of experience and be laid off at 56 years old and never find a comparable job in their field again. That is the sad part of the US job market and economy.
