Companies can give "shares" to employees, which means excess profits can be made dividends out of which employees "touch a bit".
If you would have your own company (privately own and full control) you are of course free to share the excess profit as you see fit.
Edit: and of course, share buy back avoids some taxes that you must pay, which in other schemes would have to be paid.
also boards rarely change CEOs for paying employees well, they change CEOs if the company is not growing
labor's share of income usually falls during periods of growing output and rises otherwise (but apparently tech booms/bubbles are an exception, check the graph -- https://en.wikipedia.org/wiki/Labor_share#/media/File:FRED_g... )
an unexpected but welcome change is that real wages of low-income workers increased too during the recent years, but the historic trend obviously shows the enormous disparity (check figure C 1979-2019)

and for interesting context let's not forget that during this time a lot of immigrants started to work

and for context on the context, the size of the active population also increased - so fewer people age out of the workforce than how many started working

They could, but why should they? Which advantage get the shareholders from this?
The only reason why a company with excess profits "should" pay the employees more is if
i) for a given role, the expected results of potential applicants varies a lot (i.e. the company has an incentive "to hire the best of the best")
ii) the market for these exceptional talents is tough (i.e. if the company does not hire the best, someone else will; additionally, if the company does not pay the employees really well, they will be poached)
Employees are part of a labor market. Supply and demand in the labor market drives compensation levels. When you have a rare skill that is perceived to be valuable, you can get higher compensation - e.g. Meta AI researchers getting $100M contracts or Juan Soto getting a $750M baseball contract.
As mentioned elsewhere, some companies give stock to employees. In my experience this is for one of two reasons. 1) Employee retention - stock grants tend to have multiyear vesting periods designed to keep the employee at the company. 2) Start up companies that do not have the cash to pay employees.
None of these explanations would lead to simply paying employees more with excess cash (unless the cash was created by a group of employees that you were trying to retain).
I agree that it is much more difficult for a CEO to get fired than a line employee as CEOs have significant influence in picking their boarda. However, the consequences to a company of replacing a CEO are generally more significant as well.
It's funny that people tell me they want this because they'll see some of the sales outliers. But then I explain that 1/2 or more of their salary will be dependent on some type of performance metric and most clam up.
Would that improve productivity (for that company)? Do most people refuse to work for Apple because it doesn't pay enough? Is apple limited by lack of productivity? Is Apple limited by lack of R&D budget? Would Apple release on the world more, better stuff if it paid 10% more?
Then too, most US Apple employees own a lot of Apple shares - they do get paid more when Apple pays dividends, buys back, increases the share price (/ shrinks the number of shares - same thing). Even recent Apple employees who did buy/ get the shares they could really did very well! They are shareholders.
As it is, Apple has a large number of employees in the most expensive areas of the world. It's not exactly that it's desperately skimping on employee compensation.
My impression is that Apple, still now, has a hard time finding worthwhile things to do with its profit. It generates a lot of cash, uses everything it can manage, and releases the rest productively.
the purpose of a company is to deliver maximum return to shareholders; if they're not doing that, then they're failing their fiduciary duty and the shareholders might try to force the company to change its ways
the shareholders want the money coming to them, not to the employees
(this is why the Public Benefit Corporation, "B-Corp" structure was invented, so that the company's stated purpose can be something other than simply generating value for its shareholders)
