Nah, people are pretty irrational. They really don't know what they want. Or they base their thinking on logical fallacies, like, "I already paid for it, so I have to use whatever I bought, even though I don't want to use it anymore and would not pay a cent for it at this time. I don't want to lose what I already paid."
Alternatively, if you prefer, people are rational, but the model that says rational people will act in such a way as to produce zero unemployment is wrong.
