This is kind of why I ultimately find cynicism to be inherently lazy. This is coming from a very cynical (and often lazy) person.

It takes no effort to be cynical, I can tell myself "everything sucks and I shouldn't care because nothing matters anyway" and justify not doing anything I want. I can justify not voting, I can justify not helping someone if I see them struggling on the street, I can justify not even improving myself.

In the last couple years I have been trying my best to override my cynical tendencies because ultimately I think that they are bad for me. I vote in every election I am able to because even if it's infinitesimal, I at least tried to do something to avoid whom I deem bad people getting into office.

Your comment is extremely reductionist and reverses causality for a large number of voters. Both political parties have multi-decade track records of aggressively supporting pro-corporate political agendas at the expense of their constituency. So in light of literal decades of watching prospects decline regardless of which party is currently in power many voters (correctly) conclude that their vote will not lead to meaningful change.
