Your top performers know they are the top performers and they know they have options. They will be the ones to move. The only factor that would deter that is golden handcuffs. They will be left with very highly paid, high performers who are not happy and mid to low performers who have fewer options or less impetus to move.

They won't be the ones to move because these companies are not stupid. They have mechanisms to save top talent by making exceptions for them and giving more equity.

I think you are giving more credit to corporations than you think. The exceptions are for top brass, not top ICs.
