Ideal culture vs. Real culture

Ideal culture is a term used by sociologist to refer to the idea of how we should be or what we should strive for.  For instance most people spend their whole lives in the pursuit of money because we are led to believe that if we get enough of it our lives will be better.  On the flip side, Real culture is a term used to describe what we actually do or our "norms".  For instance I shouldn't, but I can eat this entire bag of potato chips.
