For a long time, the people in charge of America’s money supply believed that if too many people had jobs, prices would automatically go up, so they would deliberately slow down the economy to keep workers from having too much power. New Fed Chairman Kevin Warsh is breaking from this thinking, arguing that a strong economy, affordable prices, and plenty of jobs can all exist at the same time. Think of it this way: the old rule was like a doctor who kept you just sick enough so you wouldn’t “overdo it”, and Warsh just threw that rulebook out.
