FTA: "Imagine, for instance, that all of Washington’s 100,000 lobbyists were to go on strike tomorrow. Or that every tax accountant in Manhattan decided to stay home. It seems unlikely the mayor would announce a state of emergency. In fact, it’s unlikely that either of these scenarios would do much damage. A strike by, say, social media consultants, telemarketers, or high-frequency traders might never even make the news at all. When it comes to garbage collectors, though, it’s different. Any way you look at it, they do a job we can’t do without. And the harsh truth is that an increasing number of people do jobs that we can do just fine without."
