I think it's a pretty good measure to include. It can act like a catch-all for what other measures don't capture. And, as we've seen, it's a pretty good way to forecast changes not likely good for democracy.
I've noticed a correlation with poor opinion of the government and willingness to accept undemocratic actions. A lot of people give a cynical quip and check out.
When Biden gets elected, they'll change it back and celebrate a successful democratic transition. A restoration of human rights and liberalism.
The world will be wonderful again. The press will be free again. Maybe they'll even give him a peace prize in the first year, right before he launches several large wars and destroys several nations.
This is kind of ironic because one of the reasons the US and its government has generally been as successful is because of a distrust of democracy and the government. Democracy is just another term for mob rule. Just because it is rule by the will of the majority doesn't mean it is flawless. For example, a true democracy also has the ability to vote away the democracy. What the founders realized is that most forms of government had their problems so they set up a system of checks and balances to curb the worst of various styles of government they considered.
People from lesser populated regions can't trust a government based on population and people from highly populated regions can't trust a government based on equal geographic representation. Marry the two ideas to mitigate the impact of government.
Government is an institution that can never be just trusted because at the end of the day it's run by people, who may or may not have your best interests at heart.
You are mistaking cause and effect, I believe. If a government behaves in a way that earns trust, trust increases. If it behaves in a way that earns distrust, trust decreases.
I actually think that widespread perception that the government is corrupt increases corruption. If you think you can bribe an officer of the law, or a judge, then you might try. If an officer or judge believes that it wont' be reported or that nothing will happen because of it, they may ask for a bribe. If Republicans think Democrats are cheating in elections, then Republicans are going to cheat to even the odds.
