> but Google or Tesla or someone might offer them $600K just to prevent competitors from having access to them
This arguments fails on so many dimensions that it must just be a meme. I’ll use Google as the example. For it to work Google has to be able to monopolise the buying of talent.
Most damning, the premise itself is self defeating. Somehow Google is picking the most talented people (delivering far in excess of say $1M marginal returns), yet somehow it is paying well below that to steal that talent and furthermore Google is then wasting that talent (employee delivering value below their pay+overhead). To assume Google chooses to waste talent merely to achieve some low value outcome (damaging a competitor by $1 doesn’t magically enhance Google’s returns by $1 so the factors are way out here) seems to assume the Google is somehow acting against their best financial interests. I don’t think Google is as poorly run as that.
Also:
1. Occam’s razor: Could it be that a Google is actually getting good value by paying very high salaries?
Yes. The average revenue per person for Google is about 160G$ / 115kiloemployees = 1M4 per employee. I do note that using an average is silly because the value distribution is not flat, but neither is the employee salary distribution flat. But the figure is so large, average does say something useful for back-of-envelope calcs.
2. Can Google monopolise by buying power alone?
No. Other companies have similarly high returns per employee (Apple is 260G$/160kiloemployees, Netflix is 20G$/20kiloemployees) so for Google to outbid them, it needs to outbid above the marginal revenue per employee, which clearly is well above a 600k$ salary.
3. Can Google corner the market for talent by restricting supply?
No. We know that there are plenty of talented developers because Google isn’t the only company making over $1M revenue per employee. Google employs about 115000 people. Let’s say 50000 of those were “overpaid“ to remove them from the competitors. If the total pool of equivalent talent were as small as 250000, then Google couldn’t monopolise talent. Yet other companies with high revenues per employee have a sum total of employees higher than 250000. Furthermore Google’s returns per effective employee become ~$2.8M/employee, so Google can obviously afford to pay $1M for talent it really wants!
