An International GDPR seems increasingly necessary. Stop trying to right size, hide prices, etc; just give straight good deals and sell good products at good prices.
I don't disagree that price gouging occurs in many markets - and I agree that an international GDPR would be beneficial to people - but good pricing also doesn't just occur naturally it's a product of experimentation.
Sometimes that's razor-thin margins. Sometimes it lets you get away with high margins.
