Re: incorrectly communicated responsibilities, I'd look at helicopter and snowplow parents[1][2], and failing to enforce boundaries[3]. I'd also look at the characteristics listed for Gen Y in Tables 3&4, from[4]. For adequate training solutions, I'm mostly extrapolating from the parenting methods of my peers. They are all current or former military and with children aged 8-18. The guy with a "helicopter wife" is frustrated with his feckless, irresponsible 15yo daughter. The other guys seem to be getting far better results from their training and discipline methods, which are roughly:
1. Do a joint task (typically some household chore) with your child, and instruct them in how to perform it.
2. Assign them the task to execute independently.
3. Most importantly, hold them accountable when they fail. "No, I'm not going to break my neck to clean your clothes at the last minute. You were tasked with doing the laundry. You didn't. So now you can go to school and get teased by the other students for being nasty. Actions have consequences. Next time fulfill your responsibilities and successfully execute the task you were assigned. I'll provide remedial training if you don't understand the task, but I'm not going to do your work for you."
4. Help your children understand that the world is dangerous, no one owes you anything, and reckless actions have life-destroying consequences. Teach them how to do proper risk assessments. If you go backpacking in the hills of Morocco, with no security plan, you might get your head cut off. How are pairs of young white women not anticipating that?[5] If you verbally or physically assault law enforcement....you might end up in handcuffs or arrested. Yet we see people having total mental breakdowns when put in cuffs, as if it never occurred to them that a reaction was even a possible consequence of their belligerence. That complete failure to assess risk is how we end up with 31&32yo LAWYERS throwing firebombs at police cars....and subsequently facing 5-20 years in jail.[6] I think this point needs to build up #3 above, because your kids first need to learn their own role in their success/failure or happiness/suffering before you can work through courses of action/decision trees/risk assessments in various other real-life scenarios they might face as young adults.
5. "Train the trainer" mentality. As I am teaching you how to DO, I'm also teaching you how to TEACH. Be cognizant that our mentorship of our children should also give them mental models, anecdotes, and body language cues for how to train their own offspring. This is mostly applicable for the >22yo adult offspring, hopefully we haven't screwed up so bad that our kids are popping out babies much younger than that.
