>Most people aren't willing to make financial sacrifices to help people they don't know EVEN if they might be affected by another person having the same belief.

Because in the US that's the case because people give a shit about cost - you could make financial sacrifices to help your community by buying local...but your costs of living are skyrocketing every year, the costs of your family are increasing, and the difference between buying from BigCorp (Walmart, Amazon) and from your local store (which is 1.3-1.7x the price vs BigCorp) adds up.

Sad but it's true.
