The high income tax rates in the 1950's were paired with a corporate tax system that allowed companies much more generous deductions for things like business lunches, business-travel-with-spouse, and so forth. Right now you pay Rick Wagoner a squillion dollars, and he entertains important people on his own dime; in 1955, you paid him less, but he expensed all his entertaining to the company. Descriptions of 1960's expense account procedures for even entry-level management are enough to make this journalist rather faint with envy.
This difference also explains some of the difference between American executives and those in Europe; among my American friends in international finance, European expense accounts are the subject of something close to awe. This is not to say that the tax code is the only explanation; almost no phenomenon has a single cause, and I have no doubt that there has been an actual, as well as an apparent, increase in CEO compensation. But I greatly doubt that it is anywhere near as large as the taxable income figures seem to make out. Leaving founder-owners like Larry Ellison and Bill Gates aside, it's hard for me to detect massive lifestyle differences between F. Ross Johnson (the CEO of RJR Nabisco described in Barbarians at the Gates) and the current CEO of Kraft Foods (which bought Nabisco). The difference is, the current CEO gets his in cash and stock.
Though $18 million in compensation is a figure that wounds the soul of most journalists, this is probably a better deal for shareholders. A tax system which encourages the CEO to take his compensation in non-cash forms probably induces all sorts of distortionary decisions that make us all, in the long run, worse off. Now, by contrast, he has an incentive to minimise such waste in order to ensure that there will be ample money to fund his compensation.
