Social safety nets primarily, along with effective delivery of government and social services, universally available. Vote and or run for office, it’s mostly what will move the needle. You will never get more leverage as an average citizen, and the odds are you will never be wealthy enough to get this leverage with fiat (wealth is a function of opportunity and history, startup failure odds, etc).
Social Security keeps almost 22.5 million people out of poverty, for example [1]. Minimum wage increases helps millions of workers at a time.
Startups are great to get rich and cash out, but not for the improvements we’re discussing at scale. Arguably, most startups have made things net worse (the gig economy, real estate price inflation, gambling on digital tokens, etc).
I’m tangentially fond of several parts of government including functions like the US Digital Service; maybe start there if you’re a technologist. Less policy and politicking, more code, but you’re still getting to wield the resources government has to offer.
