I think you got partially there. We need more of both local and Federal government.

Having more people working on providing basic services is a good thing. We are an incredibly productive species: we need to use that increased wealth to improve the quality of life for people. Government is one way to do that.

Volunteering is nice but it’s not the answer to systemic problems. I’m glad that you found a concrete way to contribute and find joy in doing so for your community... that’s great! But it’s not something that can replace Government or public funding.
