I have met several people who stole things for fun and talked openly about it. Not to make money or to fulfill some fundamental need, but just for the thrill and to get something they couldn’t afford or didn’t want to pay for.

Purely speculating but I think that to some extent advertising has been a victim of its own success in convincing people that their self-worth hinges upon their ability to consume goods and services. If you can afford it, buy. If you can't afford to buy, borrow. If you can't borrow, steal. Just don't be poor and get caught. (Being rich and getting caught usually isn't a problem.)
So, I suppose, you may never know, huh? Because it could be.
