Recognizing that politics is generally just a scam to get the slaves to keep voting for new masters is not nihilism. Wasting money & time on politics is not ever going to change anything for the better.

Building technologies that free people from govt controls. Doing productive things to help your friends & neighbors while teaching them about govt corruption & freedom tech. Building a family & raising kids who are happy & productive & anti-authoritarian are the primary ways we improve the world. Politics is downstream from all of that. The political landscape will change once the people already have.
