You’re going to have to essentially boycott the banking sector and most conglomerates. Everyone from JP Morgan to Coca Cola to Chevron, to Axe Body Spray.
I buy local/generic brands only. No national name brands.
For banking, choose a local bank if you can find one.
Restaurants choose mom & pop storefronts. No national chains.
You get the picture.
OK, pick the worst offenders and lets go. Message needs to be sent and received quickly.
