I would argue that reduced meat can be either the result of a lower living standard or a higher one. This is the issue a lot of people on each side refuse to see, a higher standard of life can be more efficient with systems either technological or social which make it possible.

Really we need a blend of each, yes the techphobes are right we don't want to live in battery farms where only efficiency matters but also we don't want to live in the drudgery of a Neolithic existence. We need to identify and adopt systems that allow a good quality of life and enables diversity of thought and lifestyle, tech can make this possible but is unlikely to do it alone.

Yes it's difficult but we need social growth, that means people tying new things and demonstrating them to the world. We should be using our absurd luxury and wealth here in the developed nations to help develop solutions everyone can use to live a good life, instead of flexing fast cars and designer clothes we should be spreading knowledge of healthy food, useful educational and organizational tools, community project structures which enable people to work on shared goals and mutually beneficial platforms...

We have a very privileged platform in the world, we should use it to show that even the richest most well educated, traveled and socialised people prefer a low or no meat diet.
