This logic only works in a world where all employees have the same leverage as employers, such as with a labor union. In reality, in the vast majority of cases, the employers have much more leverage, and therefore non-competes aren't used as a negotiating tool for both parties, they're used by employers to stifle competition for labor and therefore stifle salaries.
