I haven't seen a starving homeless person. There are soup kitchens and shelters in cities, along with charities and of course, a fair amount of pan handling.
Do you think soup kitchens/pantries offer 3 meals a day? Can't keep leftovers without refrigeration. Most don't even offer food every day let alone give enough to keep people not hungry.
There's an expansive gulf of misery before you hit the Christian Children's Fund commercial, 5yo w/rickets starvation. I assure you that you have absolutely no clue what it looks like and what you've seen hasn't told you what you think it has.
