You are doing your students, and our world, an enormous injustice by telling them that wealth and income does not matter. Increasing wealth comes along with improvements in health, reductions in oppression, increases in opportunity – but I increasingly encounter students who simply dismiss out of hand that wealth is important. Note, I am not saying it is the “only” thing, but it is important, and very much a precondition for human betterment on a wide variety of measures.
