"The benefits of power have grown dramatically in recent years. CEOs and other C-suite types have seen their salaries surge at a time when the median wage has either stagnated (in the United States) or grown slowly (in Europe). Politicians have learned how to monetise their pull. The Clintons earned $109m in the eight years after they left the White House. Tony Blair has turned himself into a wealthy man in the three years since his retirement from national politics. But the greasy pole is getting harder to climb and, once you’ve climbed it, harder to cling on to. Companies have introduced more complicated structures—removing layers, replacing hierarchies with teams and dispersing functions around the world."
