We all know that executive pay in America has exploded during the past two decades. The CEOs of major companies once made 30 or 40 times the average employee salary. But now the nation's highest-paid execs make hundreds of times what most nine-to-fivers make. At CVS Health (NYSE:CVS), for instance, CEO Larry Merlo took home a salary 422 times larger than the average employee last year, according to PayScale.

Take a look at the list below, how much each CEO makes, and the kind of value each CEO has created during his or her tenure. Sound off in the comments section below as to who deserves this cash and who doesn't.
