For the sake of argumentation, let's restrict my call to veganism to the richest 10% of the world only.
I refuse any accusation of victim-blaming, because someone that rich is not a victim.
Besides: a victim of… what, exactly? The main victims of these issues (animal suffering, climate change, deforestation, water usage, antibiotic resistance, etc) are animals themselves. Human beings are secondary victims only, and although you can argue that rich humans will always cope better with all those problems than poor humans, it's a flimsy defence to say that you are a “victim” and that those advocating for more ethical and sustainable lifestyles are “blaming” you.
