Americans don't seem to trust each as much as they used to.

In the General Social Survey taken about 40 years ago, half of Americans said that most people can be trusted, but a poll taken last month found less than a third had trust of others in everyday encounters, as in clerks who ran their credit cards, other drivers on the road, or people they meet while traveling.

Political and social scientists say this is a bad trend, because it makes it hard for people to compromise, make political or business deals, or work together with those of different backgrounds, and in the long run that's bad news for the economy. 

And they say distrust actually leads to more corruption.
