Why don't we help each other?

There was a brief mention of the Amish and their self-sufficiency in the Capitalism topic that got me thinking, so I thought that I'd share my thoughts and start another discussion.

My understanding of the Amish way of life - as someone who is probably thousands of miles away from them - is that they are not really self-sufficient insomuch as they are insular. They don't like to rely on the government, but they heavily rely on their community.

A lot of us here are leftists - some might even go so far as to call themselves socialists or communists. But for the most part we are advocating for government to provide support, and often it's the federal government rather than their local governments. For those of you who do, my question for you is this: why aren't you trying to help out the locals. And I don't just mean your city, I mean your neighborhood or even just your block.

I'm not talking about things like homeless shelters or nonprofits, I'm talking about mutual aid societies. People are complex; they don't just need things, they need people. They need assurance, motivation, and love. These are things that the government does not provide. The US Surgeon General state we are having a lonliness epidemic right now, and that it's majorly affecting people's health. We've had conversations about the lack of a third place but an even bigger problem is the death of our community hubs. It might be a good thing that people are getting less religious, but losing the church was a much bigger hit than people give credit.

We've had many comments in the past deriding "slacktivism". When you throw your voice into the void, you have no real power. But if you put your voice into your town hall, you have tremendous power. Giving money to the government is like having one billionth of a difference to a great many people, but helping out a person in your community is a huge impact in their life which might be the one thing they need to stop them from falling off a cliff. I don't think you'll find anything more socially gratifying.

I titled this "why don't you", but I'm also very much interested in hearing from people who do community work why they do and how they manage to fit it into their lives.
