I think it’s a interesting experiment I just thought it was funny how those who don’t return were demonized.

The shopping cart theory, as written here, starts as a litmus test for whether a person is capable of self governing and descends into two paths:

1. If you do return the cart you are doing it out of the goodness of your heart and because it is correct; and
2. If you don’t you are no better than an animal, a savage, who does what is right only because there is a law in place or you are forced to.

Self-governance: Are you a good person or a monster? There is no middle ground.
