HOT TOPIC TUESDAY: In-laws

Here's the scenario:

Your Husbands younger nieces and nephews are not living up to their full potential.  Some of them don't have high school diplomas.  Some of them are not in school.  They don't have jobs, they don't have arrest records, but they're just not motivated to do anything with themselves, other than speak nonsense on facebook, drink and have sex.  You've tried talking to your husband about his family, and he's disappointed with them, but doesn't do anything about it.  Some of your nieces and nephews come to you with request, problems, etc.,  so therefor this involves you directly.   You want to help them because you feel they need it, but you don't because you fill they're just taking advantage.  What do you do?
