Just some causes that I think are mostly good:

1. Complexity - a change in exchange rates can hurt Netflix's / Google's / Apple's profit, even if all underlying numbers are correct. Guessing exchange rates is a terrifyingly difficult task, and it is just one of many complications 2019 CEOs have over 1969, let alone 1919.

2. Globalisation - rather ironically, if a company employs an extra 10% of people - no one loses their job they just add an extra 10% - the ratio likely gets larger. How is that a BAD thing that more people are employed? Mattel is the most telling in this context ($6,271 average worker salary). IMHO it's a GOOD thing that Mattel directly employs workers, rather than using a, say, Foxconn. But it makes the ratio a lot worse. Obfuscating real worker wages is bad for workers, but good for avoiding ending up on these sorts of reports.

3. Market size - a follow on from 2, if Google makes 50% of it's revenue outside of the USA, what should the ratio relate to? US workers to CEO? Or South African? A lot of these CEOs are multi-country CEOs, and that is a level of difficulty beyond what existed a quarter century ago.

4. Market forces - a law to make CEO pay public means it is signaling something negative when a CEO makes a low ratio, which drives it up. Having public records of salary makes negotiating easier for workers, and CEOs are no different, so it has had a double upwards pressure.

Just some things that have made it grow over time.
