On: Equality is prevented by the misperception that it...

[endisneigh]

The classic terms are sufficient. Upper, middle and lower class are all inherently relative terms. Everyone cannot be "upper class," or middle, or lower.

The terms might be classic (whatever that means) but the meaning varies from place to place and time to time.

Class in the UK does not necessarily have the same meaning as in the US for instance.
