Oh, "policy" is the solution? Big surprise that an article full of sample bias and partial information wants to introduce government intervention as the solution.

Some questions I did not see answered in the article:

1 Does the average "typical worker pay" include the global workforce?
I imagine all of these companies in the study operate in developing countries and would therefore lower the average worker comp.

2 What is the domestic company payroll budget now vs then? How many employees are on payroll?
The feminist movement has greatly increased the workforce (for better or worse). If company output hasn't matched this offset, overall pay has to go down. This is actually a major driver of household inequality. If 2 jobs now are economically equivalent to 1 to 1.5 in 1978, how can a single-earner or single parent household even dream of keeping up?

Sure, but those methods often have to make assumptions about significant variables or bring together variables with wide tolerance bands. The resulting "estimates", therefore, have very low confidence and should really be taken with a grain of salt, but many people see it and seem to think our species has figured out how to predict the future.

Like Dr Robert Malone?

"The study wasn't peer reviewed". What a surprise.

Interesting that this defied your expectation. 70-80% would be my expectation for myself.
