In fact, since 2004 the upper middle, upscale and wealthy have been overrepresented as a percentage of population. That's right, the well-to-do aren't just pulling their weight, they're carrying the poor folks' load, too.
I can't wait for the spin from these people.
Update: A reader, who I presume is on the opposite side of this argument, comments:
Your math looks pretty creative. 25% of recruits are wealthy. How are they "carrying the poor folks' load" when lower-mid - poor are carrying the majority (75%) of the recruiting load--by your diagram.
