Hmmm. Let's play musical chairs with the planet. I (my company, my consumption, my private jet, my yacht, etc) help accelerate impending disaster. But who cares? I (my family, friends, rich buddies,etc.) can enjoy the good life for a while longer (a year, 10 years, 50 years) and after that, frankly, we don't give a shit.
Our kids and grandkids? When you're as selfish as we are, they just don't count that much.
Does too much $ reduce blood flow to the brain maybe? Sure seems like it.
