>Which game is it? Who are the players? What is zero-sum about it?

It's the same game they're playing with AirBnB, Uber, etc. Just openly break the law and subvert centuries of built up labor laws and protections we've created to make America into a livable society, just to profit a small minority of shareholders. The players are the American people, with no choice left but live with this system because more equitable uses of this capital aren't perceived to give investors "10x returns". There used to be an agreement in the US between Capital and Labor that struck a fair deal, and this agreement has fundamentally eroded. What benefits and rights that did still exist in jobs up to this point are gone for most people. The result is a zero sum game, where human suffering is converted to shareholder profits.
