I shop with a lot of things in mind. Most of the Christian stores like Mardel's and Hobby Lobby are full of totally unnecessary stuff made in China. I can't avoid buying stuff from China but I can decide not to buy stuff I don't need from China. I always go to Ten Thousand Villages to Shop. I don't agree with a lot of the liberal policies of the churches that run it but I do believe that the items for sale there are part of a network which returns most of the money to the craftsmen. I also make gifts. and yes, I do occasionally shop at Target but not a lot. I think that the key is to focus on family relationships and faith. After that, I don't stress about boycotts. I know that the culture has a lot in it that disturbs me but I have little if any control over that. God is at work and he is in control. That's all I need to know.
But you do! "All politics is local" is the correct place to start, and the choices we make as shoppers make a difference at the local level AND the corporate boardroom level.
