Large scale short term programs can be very harmful though, e.g. Bezos shows up and gives everyone shoes and clothes, putting every shoe/clothing manufacturer (except the one he bought the shoes/clothes from) out of business, then when things have gotten better there's only one place to get shoes and clothes.

This isn't going to stop me from helping out people I meet and see in need, but as a large scale program it is (at least long term) harmful.
