Not advocating prescriptives, just sharing what has worked for me in my limited personal experience. YMMV.
I keep the initial focus on them and I first introduce myself as a blank canvas with a known role between us. "Hi, what's your name, my name is yourapostasy your new neighbor/who waves at you on your 0500h run every day/who the mailman mixes up our mail all the time/etc." Then elicit details of "their story". People pretty universally love talking about themselves. Somewhere in that tapestry are common threads, and I build upon that. I've fortunately never met someone through this approach so odiously unrelatable we could not bond over something they care about.
After that, it is a matter of time and resources put in the relationship, as long as you maintain a Nash Equilibrium. The more time and resources, the more differences you both will generally tolerate; not a linear relationship, but everyone I've met has a "clearing price" to voluntarily associate with another.
I don't think in terms of "take back power and wealth from the rich", because there are too many layers between us for me to effectively address, and it doesn't scratch my agile itch. I instead have worked towards increasing both mutual assistance capabilities and self-sufficiency at the same time, and reducing my and others' reliance upon capital in an organic fashion. My position is that the capitalists (the 0.1%) have for all intents and purposes "won". They've "taken their 'ball' and gone home". The more I can decouple from capital "churn", the more I can save of myself and those I care for. There are some extremely broken systems (real estate, legal, political, medical, etc.) in the US that take unreasonable levels of capital to access for ordinary income citizens.
Autarky isn't my goal; it's long-term consistent survival at an "acceptable" standard of living without requiring a poll tax of capital out of reach of ordinary income households. Sometimes that takes some involvement with capital, but preferably a more frugal method is used when feasible, trading off convenience/time/etc. that I have more readily available. I don't hate capital nor capitalists. I'm just (in the scheme of a US reality where booking a billion in annual individual income doesn't even place in the top 10 income list) capital poor and working around it as best I can. Let it be noted in this discussion however, that there are many US citizens who would give their left nut to be in my "poor" position; many of us by virtue of being on HN in a well-compensated industry (at this time, I never take good times for granted) are in a similar position. But if you're talking about grand "take them down" terms, I've found I've achieved far more stability, sooner, by pursuing the above path than getting all pissed about a system I have neither the capital nor power to help change at this time.
