A significant portion of the struggling are doing so because they made their bed and are lying in it. Often their impulsive, irrational, demanding, selfish, chaotic etc sides are part of it. For every grateful single mother who's just been dumped and fired you've got 3 smackheads who have been given 5 places to live and been booted out and 20 jobs that last 1 week. Better to selectively helpful than doing these open services.
