On the other hand, why should Amazon leave money on the table to be happily scooped up by other companies. Forget Tesla, Washington state was giving billions of dollars in subsidies to Boeing, while Boeing was cutting jobs in Washington. The city council of Seattle was feuding with Amazon for "for making the city too expensive". The city is complaining that Amazon is making some of their citizens too rich.
I think his frustration would be understandable as businessman, and not as envy.
Of course the whole system is perverse and corrupt, but hate the game, not the player.
