The question then is how comfortable people are with lying. Politicians are obviously extremely comfortable with it.
One problem with this position is that it does not acknowledge that the daily work of a politician consists of negotiating conflicting demands from opposing interests, while the world is constantly changing around them. Something will always look like a lie from someone's particular position, and opponents will be more than happy to point those out to exploit them for their own particular political interests.
Perspective isn't particularly important to whether or not someone is lying.
For example, if I really believe that the Earth is flat, and I tell you that, I'm not lying; I'm merely mistaken.
However, if I believe that the world is flat and I tell you that the world is spherical, then I am lying, even if what I say is correct.
This goes back to good/bad faith and intentions, which is a very muddy topic. i.e. It is nigh impossible to absolutely ascertain someone's intentions with complete accuracy.
This doesn't mean that barefaced lies are always OK. But asking politicians to always only tell the truth and only the truth is a highly unrealistic demand that no one is actually capable of doing in their own lives either.
I understand what you're saying.
Perpetuating such unrealistic expectations by saying that "all politicians are liars" undermines the democratic process because it breeds cynicism and simply turns people off politics and they stop voting and they get even more disenfranchised.
Hehehe! Good! The sooner we're done and finished with government the better.
We don't need a ruling class. It hasn't worked out well for people for thousands of years, and it's still not working out well. Why do we continue down the same path and always expect different results? That's insane.
There will never be such a thing as a politician that 100% always tells the truth as it is. That is only possible in an alternate Platonic world or maybe in Heaven.
Their level of honesty doesn't even remotely approach a level that could be considered "mostly honest". So why do we continue with it? It's not rational.
