I think you mean equity distribution.
EDIT, Had another thought after posting:
Historically, if you had a world changing idea, you had to work your way up the ladder at GE/Bell/HP to get the resources to implement it, and the company didn't grant any equity. Bell Labs employees had a ceremonial signing away of their IP for $1 during onboarding. The idea that founders keep any equity is relatively new and if it's an indicator of a trend, it's likey that equity will be distributed more uniformly in future enterprises IMO.
If you think you are more valuable that's when you start your own venture because there is no upper limit on how much you make.
Really depends on how much value one can provide.
This isn't a law of the universe. This is a property of our laws. So it is a question of "should", since the people are the ones deciding what laws to have.
