WHO'S DRIVING THIS ECONOMIC MACHINE?!? We're often taught that the economy is all about a balance between supply and demand. But this week we saw that John Kenneth Galbraith proposes something different: supply (i.e. producers like large corporations) can often determine demand. This week we'd like you to think of at least two examples of corporations that have a great influence over the preferences of consumers and/or the actions of government - ultimately driving people to purchase their products or services. Be sure to name the corporations and explain how it is that they exert this influence. Feel free to include references to articles, ad campaigns, or anything else that has helped you come to these conclusions
