I don't understand how you can believe that. So you're saying that people who have control of something are not responsible for how they exercise that control?

To a degree, yes. You’re assuming everyone who had control of something, were also parents. My parents are boomers and I can assure you that they had nothing to do with making future generation’s lives worse than theirs.
Personally, I think it has to do with work ethic.
Your parents also had nothing to do with making future generations' lives better, which is the responsibility of every human. Or if they did, they utterly failed. They might have made your life better, but even murderers and animals have the sense to do that.
Work ethic is just small a part of the picture. Obviously, however, generalizations are imprecise.
