You can volunteer to help the people who are already suffering. If you are talking about affecting major change in the political landscape, you can run for office if you are eligible.

Change takes time and effort, you can either contribute to the efforts or throw up your hands and give up.

Look at the Zohran Mamdani campaign. 26k people canvassing for him. Those are just normal people who are just like you. They are helping create what could be a new wave of politicians that are focused on helping people rather than satisfying PACs.
