Oh... I don't think it will be Walmart.
At another link which I posted earlier on this thread I believe I read that Costco has only 1/5th the wealth of Walmart. See the link below regarding Walmart influence on eduction. You may even agree with some of it. However, the point that I found most interesting was that although we may disagree with our government, we can influence it by voting and political action. But there is no control over private corporations if they control education.
