Most people dramatically underestimate how widespread their cultural moral system is. Billions of people live in cultures where scamming is perfectly moral.
Honestly, I don't think it's been fast. We're just in the final phases. It's been building for decades. Venerating making money over all else and justifying anything as long as it's profitable and you get away with it has been going on for a while. Everyone sees the very wealthy and politically connected getting away with crimes and things that should be crimes, and that culture of money above all spreads.
Corruption starts at the top, but eventually it's everywhere.
For today's whataboutism: billions of people live in cultures where buying the best-priced product and not noticing or ignoring the slave labour or environmental costs in the production chain is perfectly moral.
