It's easy to say you're doing things "longterm" for "future generations". The non-existent are the easiest people to advocate for. They demand absolutely nothing of you. And if your projected "altruism" will only really be felt well after you're dead, you aren't on the hook to show results now. They claim this is utilitarian, but it's not. It never was.
What is known is that small real changes now can affect large changes later.

Anyone who says otherwise is trying to separate you from your money.
