Something that might be useful is a general strike (see https://sh.itjust.works/post/9745322 and https://sh.itjust.works/post/31602246 also). It would be nice for more people to be unionized in preparation for that. I suspect that it would be better to start unionizing for jobs that more people have (like Personal Care Aides or people working in a retail store or fast food restaurant), since after having a union contract is more normalized it'd probably be easier for people like medical doctors or pilots or lawyers to have a union contract.
I'm personally interested in electoral reform (see !rcv@ponder.cat and !fairvote@lemmy.ca also), such that I wouldn't have to worry as much about coordinating with other people before I vote. However, it's guaranteed that someone will always be dissatisfied with the results of an election that isn't unanimous, so that might not be a complete solution. A more general solution might be to handle more things locally with voluntary organizations. Another option could be to generally devolve power to local institutions (like to a state government or municipality) or to create more independent institutions that are directly accountable to the government of the United States but can act autonomously (like the Federal Reserve System) so that less is dependent on the Congress or the President, and then to reduce the authority of more powerful institutions. If some states withdrew or were expelled from the United States of America that might help (since the power of an expelled state and a post-expulsion United States of America would naturally be more local, and the power of each would also affect less territory).
