That's not what massively increased executive pay. The stock market boom - starting from the early 1980s and accelerating in the mid 1990s to now - is what generated the hyper spike in executive compensation. You can directly trace all big increases and drops in executive compensation, going back 50 years, with the S&P 500's movements.
Jul 1964 to Apr 1982, the S&P 500 went from 84 to 109. Call it 30% over 17 years. Read that again and again until it sinks in.
From Apr 1982 to Oct 1993 it went from 109 to 466. Call it near 300% in 11 years.
From Oct 1993 to today, 24 years, it has gone from 466 to 2457.
The only reason executive compensation has soared so dramatically, is because so much of it is tied to stock compensation.
If we're talking base salary, the NBA's total league roster (~450 players) earns as much as all Fortune 500 CEOs combined.
I find it silly that transparency alone would cause pay raises or gas price increases.
I think you mean “early 1990s” and “SEC”, not “late 1970s” and “FTC”.
It caused prices to go up, since now the gas station can easily see he doesn't really need to compete much, so they just barely went lower then their neighbor. After a few cycles of that prices ended up higher.
And no, the rarity nor value of the employees skills matter, and hasn't for quite awhile now (since at least the 1980s). The view you depict is the 'free market' one, where profit always rapidly decreases to zero based upon rational competition. Tell me, do you see many companies with profit margins rapidly approaching zero?
Do you know what the result was? MASSIVE increases in executive pay. Rather than shaming companies by making them admit to paying their executives hundreds or thousands of times more than they pay their average employees who are actually creating all of the companies value, they turned executive compensation into a signal to investors of corporate health. 'Would that company be able to pay their CEO $650 million a year if it was failing? Of course not!'
This move in Britain appears to be nothing more than an attempt to radically amplify economic inequality, not reduce it. And it will succeed at that as well as it succeeded in the US.
