except that consumers do not have meaningful control over the companies and the corporate leaders do
You have control over whether you eat pork or tofu, don’t you? You have control over whether you buy a new iPhone or a used FairPhone, don’t you? You have control over whether you plan a trip via airplane or via train, don’t you?
a train ticket cross country costs thousands of dollars more than an equivalent class of airplane tickets so no, no I do not have that control
Shifting the blame to the individual plays precisely into the hands of massive corporations. People buy what is available and cheapest, and without government intervention that’s going to be plastic packaging wrapped in more plastic.
Why not both? Companies that peel bananas and wrap them in plastic for sale are garbage companies. And people who buy them are garbage people.
