> An employee who makes a valuable impact does so because they want to see the company/product succeed.
With most companies, this is a comical assertion only applicable to 20-somethings who haven't realized that their employer will betray their trust one day. At least in the US.
Until companies start rewarding longevity and favoring employees over executive bonuses when budget crises occur, employees will also be mercenary and seek out better compensation if they have the opportunity. US companies, by and large, will slash staffing or employee bonuses before cutting management or executive positions and/or bonuses during difficult times, even when they have the capital to avoid those cuts if the so-called leaders would be willing to make a personal sacrifice.
Now in the case of the posted article, the compensation is already good. So that changes the calculus ($180k/year may not be the best SV salary out there, but it's very good across most of the US, even for developers). And by leveling the pay at an already good salary it can further change the motivation of employees. But try fixing the salaries at, say, the median household income of central GA (depending on which county somewhere between $30k and $45k). Sure, the boss can say, "I'm suffering with you." But the employee is still going to seek out better pay.
