Stated more realistically, what will those people do in the mean time while we all wait for the economic structure of the world to reorient itself towards profit sharing? How long are they expected to wait?
The economic structure doesn't need to change for these companies to act as if it had, nor for these people to take these jobs if neither thing happens. All three things can be true at the same time. As I said, it was a false dichotomy. That's key to understanding the situation.
And how do you expect to effect such a change? Is it just a matter of generating sufficient outrage in your mind? Why should these people be forced to wait and suffer while you and your ilk write think pieces about silicon valley?
This is the problem with ideas like yours, there is no practical plan on offer to create the reality you are advocating for. Yet, you expect these people who are suffering right now to just sit tight. Its narcissism.
The obvious difference is that (A)'s implementation doesn't also require stopping doing some further X, thereby causing suffering among vulnerable people right now. I'm not sure how you missed that.
