Yeah, we need a lot of reforms to fix underlying problems that get in the way of progress. Some things that I think can help:

• voting reform - STAR, approval, or even ranked choice voting to better reflect the will of the people
• electoral reform - some solution to gerrymandering, either algorithmic redistricting or (my preference) proportional representation
• reduce obstructionism - in the US, I'd prefer for the House to pass laws, and for the Senate to ratify them with a high vote tally (say, 60% to block a piece of legislation)

These are large shifts in how governments are organized, and potentially could be passed through large-scale public protests, like the Civil Rights Movement in the US. The public is incredibly hard to motivate, so organizers need to be really careful about which causes they push for. My preference is the second, because I think it has the best chance of creating positive, long-term change, and it's something that's pretty hard for politicians to competently argue against.
