The US is at “flawed democracy” in the Economist Democracy Index: https://en.wikipedia.org/wiki/The_Economist_Democracy_Index
Because a functioning democracy would ban a nazi party.
I think it makes sense that both are categorised as flawed.
We can play the “whose saying it game”, or look at the arguments. Democracy is rule by the lowest - and it’s easily manipulated by the popular. Buying votes, focus on the carnal, and immediate is a clear sign of democracy in decline.
The US founders didn’t believe in democracy. More people do today, mostly out of a sense that it’s moral obligation. Very few actually will argue it leads to better government outcomes.
I mean I can start my own magazine and create my own index however I want. Doesn’t mean it’s right.
