What Mr. Walton did was something any good capitalist would do. Was he greedy? I don't know, personally. His business model was one that some stores could have copied and made a success of. Yet, most just gave up. People have to adapt to many things in business, and competition is the biggest thing one has to cope with. Having grown up in a family that was self-employed in the retail industry (we had the biggest Western Wear store in Illinois) we were faced with a lot of competition . We were a one store operation that probably should have and COULD HAVE started other stores in communities that head clothing stores and driven them underground. But, with the economy we had at the time under President Carter my father told his business partner that he didn't believe it was time. After several years of his partner's wife (she was the daughter of a multi-millionair manufacterer out in Idaho) tryinig to intimidate him into allowing them to start another store, got sick of the malarkey and sold his interest including his part in the patent of a product named "Blackrock LeatherNRich" that helps restore leather. He worked for a couple of years for a friend in the heating and air business, and then moved us to Augusta Georgia in 1983.
All that being said, Sam Walton did what any good capitalist would do. I don't fault him for that. I don't fault Walmart for having a successful business model. I do, however, believe that Capitalism needs a revamp to some degree, and a bit more regulation.
