> If one forces the median to be in the middle class then this forces the upper class to be large when the middle is small
It doesn't force the working and upper class to be equally large unless you further assume the distribution is symmetric, but yes, there is a limit to how small the upper class can be since at least half of the distribution has to be split between the upper and middle class.
