I agree with this and as the article stated that it preceded Trump. By a lot. There is only one place to blame and that is the American people themselves. They have allowed themselves to be misinformed. Sure their ignorance is exploited by conservative media and by politicians like Trump, but the responsibility lies with the individual citizens.
That means democracy is working. You get the kind of system you deserve.
Tracing reports of the downgrade back to
their source, a Jan. 2017 Economist article, what I find is
Declining trust in government is denting democracy...
The downgrade was not a consequence of Donald Trump, states the report. Rather, it was caused by the same factors that led Mr Trump to the White House: a continued erosion of trust in government and elected officials,...
A similar pattern of declining popular confidence in political elites and institutions has also been evident in Europe. Such disaffection helped cause the scores of more than 70 countries to decline compared with 2015. Although Britain is one of the leading exemplars of this trend, it was one of only 38 countries to record an improved score, thanks to the robust turnout of 72.2% in the June 2016 Brexit referendum.
Surely the same factors that led Mr Trump to the White House led Britain to Brexit, so it's not clear why those factors downgrade the U.S. and upgrade Britain. Moreover, it's not clear why anyone would think public cynicism is evidence that a democracy is flawed. If the U.S. has less trust in its rulers than, say, Canada has, that might mean U.S. democracy is less successful at putting trustworthy people into power; but it equally might mean that Canadian democracy is less successful at revealing the truth about its political elites to the Canadian people. Declining trust in government is denting
democracy's reputation. That doesn't mean it's denting
democracy. Perhaps it is those who trust their rulers more who have allowed themselves to be misinformed.
