Although deviant behavior can be bad for social cohesion, it is paradoxical because: we tend to ignore most deviant behavior. it is the deviants among us who hold society together. most deviant behavior tends to disappear if it is too threatening to social cohesion. definitions of deviance never change over time.

I believe the answer is: it is the deviants among us who hold society together.
Deviants in that referred to in the statement are the individuals who are brave enough to reject the mainstream way of thinking in society.
Almost all people that made important inventions are considered to be a deviant by society.

In financial aspects, a depression is a sustained, long haul downturn in monetary movement in one or more economies. it is a more extreme monetary downturn than a recession, which is a slowdown in financial action through the span of a typical business cycle. a depression is an irregular and extreme type of recession. so depression is always followed by recession but it is not correct to state that a depression always follow a recession.
