When we buy thing now days even if it says manufacture in the US where the ingredients come from?
might be China
You're right. I think it would be effective if we all started sending letters to companies asking where their ingredients, components, etc. come from. Lots of things there is no other alternative to buying them made somewhere else - but I also feel like there are lots of things that we can live without buying too.
A boycott would accomplish several things - it would tell the companies that they need us more than we need them. It would also show each of us what we really can live without.
I don't know about anyone else, but the older I get, the more I want to get out of the rat race and live more simply.
