You are right in that the article (or the mentioned book) does not provide any evidence at all for the radical suggestions being made. In fact, counter-evidence is discarded with a very strange "it was ambigous" hand-wave. Although, I am unwilling to believe that people who have never been destitute cannot come up with a solution - it's harder, but saying that it is impossible is like saying we just don't have imagination. [Edit: no-idea why you are being heavily down-modded. I had that knee-jerk reaction when I first read your response (probably because I tend to go leftist), but when I actually read the article in detail, yours is a very valid response.]
