How does that last part happen? Like this:
A Montana farm sold mint to an American toothpaste company. One day the toothpaste company mysteriously ceased its orders.
Wal-Mart, the toothpaste company explained, had decided that by its calculations a cheaper toothpaste could be made by importing vats of mint oil from China. Wal-Mart, known for trying to reduce costs by 5% every year, said it wanted to buy the cheaper paste and would find somebody else to make it, if necessary. The farm took a serious financial hit.
Wal-Mart’s business practices are good business. That doesn’t mean that they are good for anyone else.
