Throughout history, poverty is the normal condition of man. Advances which permit this norm to be exceeded — here and there, now and then — are the work of an extremely small minority, frequently despised, often condemned, and almost always opposed by all right-thinking people. Whenever this tiny minority is kept from creating, or (as sometimes happens) is driven out of a society, the people then slip back into abject poverty.
This is known as “bad luck.”

“We had reversed the recession, avoided a depression, gotten the economy moving again. But over the last six months we’ve had a run of bad luck.”
Barack Obama - Aug. 15, 2011 - Decorah, Iowa
