We study history in order to understand the present moment. So your question presents a false dilemma in an attempt to cut off historical analysis and blindly continue what you're doing without question. How is society actually shaped? If you believe it's by people simply "showing up," you are delusional.
I humbly disagree, at least at the local level. Get involved and you'll be surprised at how much you can do. Local clubs, like an Optimist Club or Lions Club volunteering for your community builds relationships. Many people involved are part of the community: business owners, politicians, accomplished/connected individuals, etc. Much of what affects you in a democracy is local and can be changed if you get involved. It is not just about checking some boxes every couple years.
