The parent post here is actually reasonable, not cynical.
Think about most of the things that actually influence your daily well-being and the future of the country. We need good schools with good teachers. We need natural places for kids to exercise and learn about the world. We need sane neighborhoods with low crime and shorter commutes and people who actually know and look out for each other.
While the federal government can debate and fund large projects for these things, the people who actually make them happen have boring-sounding titles like County Commissioner and Zoning Board Member. Even if the federal government funds them well, the money gets misused unless local officials use the money thoughtfully and non-corruptly. If you think the corruption on the federal level is bad, you probably don't follow your local politics very well. In most areas they involve not just corruption but also incredible, routine incompetence even on fairlay basic matters.
So if you want to change the status quo, the real tradeoff is something like this: you can either cheer someone's reddit campaign that will probably not get them elected to Congress and pat yourself on the back for trying to make a difference, or you could actually monitor and run for a local office and concretely make people's lives better.
