We can now prove that revenue has actually decreased per dollar paid to a CEO...CEOs now make more money for accomplishing less?

Your metric is a ratio and it does not prove that CEO's accomplish less.

For example, suppose a CEO doubles revenues (did you mean profit?) from $1B to $2B and their pay increases from $10M to $30M. They have accomplished more, but revenue/pay has gone down.

In my career I've made an uncountable number of jobs unnecessary through automation. But did I capture any of this productivity boost?

Most likely. Pay for programmers has skyrocketed, unlike pay for ordinary workers.

Besides, the productivity of the few people you failed to replace has also gone up. If you make 8/10 jobs redundant, should the pay of the remaining 2 increase commensurately with their drastically increased productivity?
