> First of all, Pareto Principle, so some employees contribute a ton and many contribute less.
Correct. But with very few exceptions I don't believe that any one person contributes $500m in value over 5 years.
> Second of all, having been in tech individual employees do drive projects that wouldn't have happened without them for a decent amount of time. In aggregate that moves the bottom line a ton
In aggregate, yes. But it's the systems that aggregate the contributions of the employees and turn them into profits.
> As for your second point, that's a straw men argument that assumed companies are omnipotent. The employees who drive the bottom line cannot truly prove this to a new employer so their value is diluted by those who don't.
I'm assuming you mean omniscient, and no, I'm not assuming omniscience because I'm not actually talking about a company's ability to attribute value creation, I'm talking about the employee's ability to attribute it. Any random Google employee who thinks that they contributed $500m over 5 years can't just pick up their laptop and go work for a startup and expect that startup to make $500m over the next 5 years. It's not happening. The only way that their project made $500m was as a project embedded in the enormous money-making system that is Google, and absent that system they don't make that much money for the company.
