The median is what you get if you sort all people by income and pick the middle person. 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: Example with a large middle class:
|...|...........|...|
^ ^ ^
| median |
(working) (upper)
Example with small middle class:
|.......|...|.......|
^ ^ ^
| median |
(working) (upper)
Real life example with small middle class:
|.............|...|.|
(working) ^ ^ ^
median | (upper)
middle
