So both sides identify the problem and have different ways to solve it. Keeping the two sides focused on their own method of solving the problem prevents any meaningful change. This keeps the rich ruling class in place as-is for now. Sounds like they are doing short term self preservation well.
A Dem win or a Republican win (wherever) will not improve things much, it'll just flip flop things around for a little bit and the other side will be pissed off until they win again. It's a downward spiral and I'm not seeing anything being done to break the cycle, it's just damage control and short-term improvements.
Reboot the system, change the democratic system, allow for more varied representation, reduce the power of the president (and for fuck's sake moderate their statements, Trump's twitter diarrhea was an embarrassment to everyone), etc.
