You can also organize politically to get large scale action.

If I put all my effort into politics and forget everything else, I estimate that my effort will amount to as close to zero as I can calculate.

On the other hand, by just not ordering one Widget off Amazon, I am making a huge impact, if you count all the materials mining, shipping and re-shipping, packaging and re-packaging, and so on.

The worship of individualism has a blind spot to collective action.
