George Bernard Shaw is credited with saying that if all economists were laid end to end, they wouldn't reach a conclusion. And President Truman said, "Give me a one-handed economist. All my economists say 'on the one hand…' then 'but on the other hand.'"
If you read the business news, it often seems that Shaw and Truman were right. Some economists seem to always favor one viewpoint, while others favor another. Often, it seems that their opinions line up with their politics.
