Why America Needs This:
Pick literally any year from the United States' modern history and read some news from the era. Just ... any year. Now, ask yourself: Is this not a country that would benefit from a few weeks of annual chillin'? Even your news media could really use the break. For the few glorious summer weeks when the whole country is in off mode, we mostly get calm, soothing news about badgers and s**t unless something particularly pressing happens.
Even if you miss the work, you can always simulate the experience by letting the seagulls poop on you.
Oh, and there's also the fact that the U.S. is currently the only advanced country that doesn't require employers to provide workers with paid vacation time. You know that old stereotype of Japanese salarymen working themselves to death? These days, that's the American workforce.
Every once in a while, some politician does point at the situation, but Washington has been so aggressively disinterested in providing Americans with paid downtime that you'd almost think that they were working for the companies instead of the little guy. Most recently, some guy from Vermont called Bernard Sanders pushed a bill that would have guaranteed at least 10 paid vacation days to all eligible employees, but it died a pauper's death in Congress earlier this year. (You probably missed it because 2017 politics have been a dumpster fire. Also, you were probably too busy working to hear about it.)
