I believe in Capitalism and I hope you do to.. But in oursystem we cant possibly regulate all companies to the point whereeveryone is behaving the way we want In our system we asconsumers have the ultimate power and either buy a product or notand thus make a company a success or a failure.Having said that how can we as consumers make sure companies arebehaving and doing business in an ethical way? Please tell me howwe can monitor and pressure companies to operate ethically. Pleaseno government based answers.
