According to Wal-Mart, its main goal is "to benefit the American consumer". Does the Wal-Mart economic and social model benefit the American worker as well?

Abstract

Very few European people have heard of Wal-Mart. But the company plays a central role in the lives of millions of Americans, who rely on it for their food and other necessities. For some, Wal-Mart, with a presence in the entire US territory, is the symbol of a certain 'American way of buying', associated with super-low prices and extended availability. But Wal-Mart would be nothing without the people it employs. People who load and unload lorries, people who stack shelves, people who work at the check-out places and also people who manufacture their products. How does Wal-Mart impact the lives of these workers?
