I think the root of it all is that they just want everyone to remain a child. No thinking for yourself, do as we say, not as we do. No growing up into a person that can fully function on their own.
Some people in life just like it this way, they don't want to make the hard decisions. They want to be told what to do with a big part of their life, it just makes it easier for them rather than having to go out there and find it on their own.
Frustrating as fuck for the rest of us however.
