Alas, what you say applies to so many more countries than just the US.
In my opinion, we need a new, more evolved version of democracy. It seems that most (all?) variants of modern democracy suffer from the same issues:
1. Imbalanced media ownership.
2. A party winning elections. It would be better if parties shared decision making based on proportion of public support. Yes, many governments are meant to work that way by voting in parliament, but in practice that doesn't seem to actually work due to reasons such as party loyalty and ...
3. Decision making ministers/senators. I get that minister/senator are different roles, but my point is that each person is responsible for far too much. Instead we ought to have spokes people and team managers, but actual decision making should be left to specialist teams, a form of democratic technocracy.
Reasons for 2 & 3 are:
- No one party or senator/minister to lobby or bribe.
- Because all parties can expect to be partially in power uninterrupted for the long haul, that ought to reduce short term thinking.
- You don't have politicians making decisions on topics they have no training nor experience in (in my country most politicians are lawyers) such as various technologies and sciences, education, medicine, etc.
The problem is, of course, getting career politicians to agree to such changes.
