Third parties in the US are almost exclusively tools for siphoning votes off the main parties.

But if you still think government runs the show you are out to lunch. Corporations have been dictating policy for a long long time in the US, and the laws are only making it easier for corporations to directly own politicians.

The only one who will change this is if a huge amount of voters organizing and demanding change. Like current levels Republican stochastic terrorism, but for things like healthcare, education, workers rights, consumer rights etc.

Corporations spend a lot of time and money taking these things away from us, and we’ve been generally watching the middle class disappear for decades.

It will take sustained, active, pressure, and vigilance from the people to make corporate money is not worth it and politicians make decisions based on benefitting their constituents.

Unfortunately, nowadays most constituents only care about making life difficult for others instead of better for everyone including themselves.
