The common denominator is the pyramid scheme.
Obama promises to "spread the wealth"
Socialism promises to "spread the wealth"
Pyramid schemes promise to "spread the wealth"
The only difference between the three is who the wealth distribution actually goes to.
We've likely heard the $50k-a-month advertisements on the radio. Youtube has a funny video that explains it as a "reverse funnel" (which looks remarkably like a pyramid). You would think that someone who claims to make $50k a month would have better commercials, after all the guy "makes" $600k per year luring suckers into his scheme.
Likewise throughout history socialism has claimed to be the vehile of equalising the rich and the poor, yet every socialist experiment foisted upon mankind to date always winds up as an oligarchy. A few very rich leaders and a boatload of very poor handing over what little they have to support the ultra rich leaders.
Then, there's Obama. He won;t let on to his faithful followers that they will be screwed along with everyone else. Many of Obama's supporters earn significant six figure incomes and would be punitively taxed under his "wealth re-distrubtion" ideals. Somehow they seem to think that they will be among the oligarchs in the power class. How sadly wrong they are. They only need to look at History to show the ugly truth of socialist agendas.
