I agree that if you split the CEO pay it does not affect so much the employees.
I just wanted to highlight is that the CEO does NOT want the employees in the board as they may see the CEO's salary as unfair. So, to protect his own salary, the CEO keeps employees out of the structures of power.
Then we can argue if is that lack of power the one that keeps or not workers salaries low. But workers are not represented becuase is against the CEO best interest so her own salary can grow unchecked.
If it's a low margin business, it will go bankrupt.
Note that in the past several years, shareholders have experienced massive returns due to rising corporate profits, largely because corporations have held workers' wages stagnant throughout the economic recovery/boom.
