While I agree the advertizers are very much to blame, we the people have a massive responsibility here. Giving a gift is supposed to show you care about someone, that they are in your thoughts. So I think we need to step back and analyse why its necessary to give so many gifts, a few for your nearest and dearest should be enough.
My partner and I haveset a budget for gifts this year, as buying more doesnt make us love one-another more.
