Not enough people seem to understand that you will have to sacrifice things for the sake of sustainability.

For example

There is no way to supply the amount of meat consumed sustainably. It doesn't matter if you cut off every billionaire's head and send all meat profits directly to industry workers. It does not change that people currently eat more meat than can be produced sustainably.

There are so many other cases where this is true. It's not just rich people and corporations. They are an entirely different symptom, solving one will not solve the other.
