You are misreading a descriptive take with a normative take. The problem is that defined benefit plans are not possible. If you actually care about old people, rather than caring about scoring internet points yelling at people online, then the correct solution is to understand the problem, and start dealing with it. The "yell at anyone explaining that defined benefits plans are impossible and then give out defined benefits plans anyhow" is what is and will continue to hurt people. It's not people like me hurting people, it's people like you who insist on living in fantasy because my gosh isn't the fantasy nicer than the reality.
