I used to work bringing in carts at a store and it was the best part of my job. I see this as just a cost of doing business for these giant stores that need carts to begin with, although I always put my cart back. I can understand if the thing is way far away though. Who cares? Let them pay someone a fair wage to keep track of them. We know that will never happen though so you need to bring it back to be considerate to other shoppers. Giving the store free labor lol
