Utter B.S.. For a group the worships money, they do a pretty crappy job at actually obtaining that money, that would include liberals also. The bar has been set pretty low, a household with $500k in retirement accounts makes it into the top 10%.
There is only one group that puts a lot of focus on "other people's money". Republicans on the other hand are just trying to hang onto what they earn so they push back on policy's that would pinch them personally.
