Political Memes

Logistically, ie making sure the food is still fresh or good Legally (as in the US it’s illegal to give food to the homeless in some places) There are some CSR initiatives from supermarkets like Lidl but in a capitalist society it’s just not profitable for the supply chain. Maybe a nightmare is too dramatic, but highly improbable in current society as it stands.

I completely agree. Things like anti homeless architecture, shelter quality and the housing voucher system (and consequent rent gauging) are obscene.

Ending homelessness would take way way less money than the current system, but the capitalist elites need a threat to barely making ends meet workers so they don’t have time or energy to worry about their neighbor.

If it is something for the homeless people inside the same city, it's fine. However, I was thinking about the scenario where food would get transported from the richer parts of the world to the poorer parts of the world. In that case, I do not see the viability of a "last chance" - part of the food would still get spoiled and thrown away, unless you want to feed the poor some spoiled food.

I'd rather see more people educated not to buy too much food in the first place, then direct the remaining to the poor (and even, if possible, produce less in the 1st place. Have fewer cows, less agricultural land and more wild terrain (forests and the likes) if possible).
