That's part of the reason states went to deposits...heck, there are people that make their living (such that it is) by walking streets/roads picking up bottles and cans and turning them in for the deposit. It was big business for the homeless in NYC.
Funny story:
Back in the small town I grew up in, one summer evening I was watching a slow-pitch softball game that some friends were playing in. I was enjoying a chilled adult beverage or two and a local character came up and asked me if he could have a one of my brewskis. He was a guy from the local half-way house (he was what they called mentally retarded back then.) He did odd jobs around the town for spending money (including collecting bottles and cans for the deposit)...but anyways I give him the brew and the son of a gun opens it up and proceeds to dump it on the ground just so he can get the deposit!!!!
