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.
These kinds of articles like to play tricks to paint a narrative. Take this paragraph for example:
>Yet overall CEO pay continues to increase. According to Institutional Shareholder Services (ISS) the average pay for a CEO in the S&P 500 grew from $11.5 million in 2013 to $13.6 million in 2017.
Notice how it says "overall CEO pay" but then goes on to cite statistics for the average CEO of an S&P 500 company? It's a very common tactic whenever CEO compensation is discussed.
CEO pay is increasing for these companies though and one reason for it is that these companies are becoming bigger and bigger. This means that a CEO is responsible for more people and companies want more qualified candidates for that. Meanwhile the median employee usually doesn't have additional responsibility compared to the past.
Let's look at Walmart and a corner store. The clerk working at Walmart and the clerk working at a corner store roughly have the same responsibilities. On the other hand, the CEO of the corner store is responsible for 5 employees, but the CEO of Walmart is responsible for 2 million employees and this responsibility is growing.
Edit: I'm not saying that this explains the entire difference, but it's definitely one part of it.
