What is the majority of the United States economy based on?

You know, it's funny when you think about what really drives the US economy. What's it mostly made of, right? Well, it's actually services. Think about it... where do most people work? My aunt, for example, is a nurse. My best friend's dad works in finance. My neighbor is a teacher. All services! Then you've got everything from the guy who cuts my hair to the barista at the coffee shop I practically live in – it's a whole world of services! Of course, we still make stuff, and trade is a big deal (I mean, where'd my phone come from?!), but services like healthcare, finance, education, and even things like entertainment – concerts, movies, Netflix, you name it – those are huge chunks of our GDP. It's kind of mind-blowing when you realize just how much of our economy isn't about making things anymore, but about doing things, you know? It really makes you think about where the jobs of the future will be, doesn't it?
