Because big corporations like Walmart store money into offshore bank accounts so they don't get taxed properly, so that's money coming out of the economy and not going back into it. In addition to that, they pay their employees horrible wages that result in a lot of people drawing welfare, which results in more money being lost and tax payers paying even MORE. Whereas other countries have been doing this for a while and are doing just fine. It's because people think socialism = communism and people think we're still in the Cold War.
