That's a non sequitur. What you have cited isn't Tesla giving its employees Elon's Tesla shares. Yes, Tesla did offer Elon share options. He still has to pay for them with his own money. The reason why these options are lucrative is precisely because the company (funded substantially by Elon placing his own wealth on the line) has risen under his stewardship.

Great, so bring a union in. Maybe median wages will briefly jump 10% or so in response to threats. Within five years the median wage probably won't be any higher. Probably lower if union action rattles investor confidence and Tesla's access to capital shrinks, leading to less future investment, in turn leading to less profit and fewer jobs at the company.

With all this talk of bringing in a bloated Detroit union bureaucracy into Fremont, you might as well plead with Tesla to focus less on US manufacturing over the next decade. Yay, everyone wins!
