He owns a lot of companies and keeps his distance from their reputations. Companies make money and stay on top by doing awful things. Think about coca cola and plastic pollution. Buffett has to own that when he has a controlling stake.
What’s the counter-factual here? Coca Cola not allowed to exist? Plastic not a permissible material for soft drink bottles? Nobody allowed to drink soft drink? Companies forced to clean the streets?
I dislike plastic pollution as much as you do, but your elected representatives have more responsibility here than Buffett.
Imagine what a world we would live in if people held themselves to the same standard they hold billionaires to. After all, coca-cola would change their ways pretty quickly if people stopped buying things over the issue.
Berkshire owns less than 10% of Coke. That’s means Berkshire’s voice is represented in the boardroom, but is more than a factor of five from the common definition of “controlling stake”.
