I am reading "The Anarchic Order" by Anselme Bellagarrigue and "The Sociology of Pierre Joseph Proudhon" by Constance Margaret Hall.
My only suggestion is that much of Errico Malatesta's writings are better than Conquest of Bread. Don't take Conquest of Bread too seriously, in my opinion.
I don't agree with your framing. What is important is not to shame leftists with higher income, without centering them. Higher income leftists should quietly support the voices of the worst off, ideally, and avoid centering themselves.
