Btw, I think Google could already either pay 70k+ to every employee or is pretty close. They just need to make sure that all the janitors and baristas are employed by subcontractors.
Subcontracted workers are technically not employees of Google, therefore can be disregarded when making claims about the min salary of employees.
It's all a bit tongue in cheek and silly.
It does have some real world consequences because of some regulation that requires companies to publish some information about the ratio between CEO pay to lowest paid employee.
But as we noted here, who is officially an employee and who ain't is flexible.
Uber and eBay and Amazon are an even more extreme example: Uber drivers and eBay sellers are at the heart of what makes those companies tick. But they are not employees.
