So you can scoff and snicker all you like at the shaggy, hangdog 27-year-old next door dressed in a baggy college sweatshirt and cargo shorts, taking empty pizza boxes and beer bottles to the dumpster. He could be a loser just trying to extend his adolescence indefinitely—or he might just be getting ready to change the world with what he creates in his unkempt guy lair.
Or, or, you know, hear me out here, I know this might sound crazy, he could just be content with living a nondescript life of simple pleasures, having seen plenty of reasons in his 27 years to doubt that marriage, parenting and mortgages are really all that. No, you're right, that does sound crazy. Let's just reheat some leftovers from Atlas Shrugged and justify his existence by the tiny fraction of a chance that he might come up with some world-shaking invention.
