I'm not sure my parents are the type of people who would have saved for retirement had they never become Witnesses, but it certainly didn't help.
My dad just decided to stop working 15 or so years ago in his early 50s. He didn't have a penny saved for retirement but he'd had enough. My mom continues working to this day. My dad eventually starting drawing social security when he turned 62. He's now a few months shy of 70.
My father's health is now such that he probably couldn't work anymore even if he wanted to. In the meantime, I dropped out of JWism in my early 20s and have been laser-focused the past 15 years on building a career.
It's a tough situation. Do I take some of my own resources that I have worked hard to obtain and hand it over to them? In some respects they deserve to reap what they've sown. They'll piss it away on nonsense anyway. On the other hand, they're my parents, I love them, and I don't want to see them struggling.
I've given them tens of thousands of dollars in monetary assistance over the years, and it hasn't really helped. Their house is still filthy and they continue making stupid decisions in every walk of life. At least JWism has provided a distraction.
