When I visited Yellowstone, I saw recommendations not to feed the wildlife, along with explanations of why it is a bad idea. When they are fed, they lose the ability to forage for themselves and they become aggressive when they do not receive handouts. A wild animal that has become accustomed to handouts is far more dangerous than a wild animal that fends for itself.
It seems to me that these characteristics apply equally well to people who are conditioned to depend on handouts.
The animals of which you speak are best described as ferals
Bravo! Excellent analogy.
