So today we're going to talk about globalization, and in doing so, we're going to talk about why we study history at all. Ooh, ooh, Mr. Green! Yes, me from the past? We study history to get a good grade, to go to a good college, to get a good job. So you can make more money than you would otherwise make and be a slightly larger cog among the 7 billion gears that turn the planet's economic engine, right? And that's fine, but if that's why you really study history, then you need to understand all the ways that the t-shirt you're wearing is both the cause and result of your ambition. This t-shirt contains the global economy, its efficiency, its massive surplus, its hyperconnectedness, and its unsustainability.
