I just thought of something.
Some people have very hard time letting their children go (I mean everyone had hard time but ultimately you get to let them grow up no matter how you feel). But some people just can’t let the kids go so they deliberately or subconsciously cultivate dependence in their children.
If they are jobless and homeless, they aren’t likely to ever have their own homes/families and move out, let alone more far away. So these parents will never be lonely and alone and experience empty nester syndrome as their kids will never fully grow up. They might complain about their kids but deep inside they don’t want their kids to grow up. So when we think we’ll save these people by teaching their kids independence, ultimately it’s not what these parents want at all.
