Self checkouts help to reduce the store's overhead, which hypothetically at least means that you get your groceries at lower cost; so, from a certain perspective, one could argue that the store actually is paying you to use them.

I don't know how things work in the world to the south, but here in Canada we actually have value-brand grocery stores. They're the sorts of stores where the customer bags their own groceries and where things like self checkouts were first adopted (along with charging for disposable grocery bags).

EDIT - meant to address the job thing, too. It's an odd bit of obstinance; redundant and unnecessary jobs get eliminated. It's a part of progress. Self-checkouts mean that fewer cashiers are necessary, so fewer get hired.

There are a lot fewer traffic cops than there used to be, but I don't hate stop lights.
