As it happens, the keyword in your post is strawman. Since you're so hung up on Trump, he had been a lifelong Democrat prior to running as a Republican candidate. Do you not see the futility of such labels as liberal and conservative? It wasn't Trump that drove the US off a cliff but the people who have been utterly blindsided by party politics!
That's the funny thing though, they're all the same on either spectrum. It's not like either side cares about the people or anything, it's just what they can do to get more votes and keep their influence going. They just pander to different groups and exploit them in different ways.
It's not something exclusive to democracy or capitalism either. Look at any governing system in the world and you'll see the exact same thing.
Hell, I haven't seen a difference regardless of president since Clinton. It's all been the same to me (aside from Clinton's housing market fiasco), but even then it never actually effected me at all. Clinton was Bush was Obama was Trump. They pretend to care about certain groups, but really they don't. The only one I think who might actually care is Trump, but not because he cares about the people, but because he cares about the overall perception of himself (even then it's for self-benefit).
All you can really do is live and let live. Even if people managed to radically change the governing system or the people running it, it'll literally end up in the same situation anyways.
