I think it is time that you started talking. Tell her about YOUR values: paying what you owe and on time, avoiding debt and living beyond your means. If you want, complain about subsidizing those who don't play by the rules, but try to change them after-the-fact. If you read the newspaper or watch TV news, there is bound to be some story that gives you an excellent opening. Don't make your comments in answer to hers, but to general news that matches hers.
As for her daughter, let the mom know that your not going to be able to continue watching her without compensation, or else find a reason why it simply will not work at all. If you do still spend time taking care of the daughter, make sure to impose the same rules on her as you do on your own daughter--part of being a child care provider is helping to shape the social behavior of your charges. That said, I agree with most of the comments that the girl is simply talking about her life. Give them both other things to talk about: suggest crafts or projects they can work on; ask about school and get them talking about that; tell your daughter to tell the other girl about something SHE has going on htat she is excited about; etc.
Keep doing for Grandma because that is the right thing to do.
