The shopping cart is the ultimate litmus test for whether a person is capable of self-governing. To return the shopping cart is an easy, convenient task and one which we all recognize as the correct, appropriate thing to do. To return the shopping cart is objectively right. There are no situations other than dire emergencies in which a person is not able to return their cart. Simultaneously, it is not illegal to abandon your shopping cart. Therefore the shopping cart presents itself as the apex example of whether a person will do what is right without being forced to do it."
"A person who is unable to do this is no better than an animal, an absolute savage who can only be made to do what is right by threatening them with a law and the force that stands behind it"
"The Shopping Cart is what determines whether a person is a good or bad member of society." Anonymous
A very "social" thing to do. On the other hand there are people working at the store who are paid to do this, and I as customer pay a small amount of their wages when I buy my food there.
So it seem to me that in your society, the people who retrieve shopping carts for a living would all be out of work, and I am still paying for it.
