I'm curious why you see my comment as a defense of shareholders?
The beneficiaries of faster transportation, abundant food, and vast material wealth are the consumers. The shareholders only benefit indirectly in that they can take their money and consume goods and services that others have produced.
That's a tradeoff that happens no matter what economic system we choose. I'm also not even suggesting that we pull back on addressing climate change; I'm saying that this is an ineffective way to advocate for it.
