The "wellness" industry is a way to scam rich people. You
want to believe you can spend your money to opt out of environmental toxins by shopping at Erewhon. But you're still going to be exposed to all of this stuff unless you live in a hermetically sealed bubble and never leave. Or if you get rid of toxins in your area, an action which affects everyone.
The hard truth is that pollution and environmental toxins affect everyone present in that environment. Taxes and government regulation are going to do far more for the wealthy than individual changes in shopping habits.
