In many places vagrancy is.
But your common college drunk is not living on the street every day, causing a blight, begging for money, food, etc… and is not the one we’re trying to help here, are they?
But according to your ilk the only way to help the homeless is to give them everything with no effort on their behalf in exchange to try and help themselves using the resources given to them. Either that or insist that our entire society go through an evolutionary change for the benefit of a relatively small percentage of the populace that it simply isn’t going to go through.
