Why hasn't this same state destroyed Asian, European, Hispanic and other White families? If the root cause is truly the Welfare system; one would expect similar reactions across all races and cultures, wouldn't you?
I submit that the root cause lies in 'Black Culture', where they worship living the 'Gangsta' and 'Thug' lifestyle, where 'Ho' is a compliment, getting away with a crime is something to be admired, and continual discontentment is maintained by claming 'victimhood'. This culture requires no effort, no education, and no effort to actually 'earn' money - emphasis is placed on remaining ignorant, and getting everything 'free' that you can - whether it is stolen, or a welfare check, makes no difference at all.
You don't see this same of 'ethics' in many Asian, European, Hispanic or othe White cultures. In these cultures; the concept of 'honor' actually has meaning, however this concept is dimminishing in the Hispanic culture in the past generation.
The culture to which you refer actually came after the welfare state,
and I believe the left intentionally targeted the black population (community organizers or whatever they were called back then) for dependency, because they viewed them as inferior sub-humans incapable of thinking for themselves.
