From Pew Research Center:
Trust is an essential elixir for public life and neighborly relations, and when Americans think about trust these days, they worry. Two-thirds of adults think other Americans have little or no confidence in the federal government. Majorities believe the public's confidence in the U.S. government and in each other is shrinking, and most believe a shortage of trust in government and in other citizens makes it harder to solve some of the nation's key problems.
As a result, many think it is necessary to clean up the trust environment: 68% say it is very important to repair the public's level of confidence in the federal government, and 58% say the same about improving confidence in fellow Americans.
Moreover, some see fading trust as a sign of cultural sickness and national decline. Some also tie it to what they perceive to be increased loneliness and excessive individualism.
