Fair, but perhaps they’d also work as hard as the CEO if they were paid the same and had equal preferred founder shares instead of common shares. Also, when was the last time you heard of employees with equity getting a secondary to take money off the table vs founders getting to do so? It’s not the disparity per se (because at some point, there is a demarc between the population willing to sleep on the floor and eat ramen for org success vs those not and a corresponding comp delta), but the disconnect between the disparity and the output expectations.
Edit: I’m aware of the VC backed share structure. My thesis is if you want more ownership in your dream from your employees, give them more equitable ownership in the enterprise.
