The only surprising thing here is that liberals could assemble the skills to become billionaires. Of course, they may have accumulated the wealth through various very efficient means while being ruthlessly apolitical, then only later, looking back in remorse, chose to don the sack cloth and ashes, calling for all the new restrictions on others, so none may follow in their footsteps.
For the most part, few of them chose to become altruistic philanthropists, preferring to trade their position of wealth for a position of power.
Not really you must realized they that liberal elitism is a lust for power and control over other (us the great unwashed)...in the super rich class have not just people with a lust and drive for money but also a lust and drive for power and power over others...
after all if the left real concern was about the poor and downtrodden as they claim... they would just give money out directly to them...not spend on political campaigns to get power....
To see the truth see where "There Money - vs - There Mouth" is....
There mouth may be "for the poor" but there money is "for power"
