Of course Walmart has put some places out of business, but it's hard to ignore their sheer convenience. Does anyone still complain that we don't do most of our manufacturing in our own countries anymore? Of course not. I can understand that people will sometimes want a company that understands their community, like an Ottawa windows installer, but more often than not, convenience and cost are hard to resist.

Yes, people will inevitably lose from Walmart. With that said, some changes are difficult to resist, and for a reason. People also benefit from Walmart through significantly lower prices.
