Most of these super-rich are socialists.
All the socialism in America has only served to widen the wealth gap, create millions of working poor (see Fed currency devaluation), ruin our moral fabric, transfer power to the few, make bankers even more rich, lower labor participation etc. What’s not to like?!
Go figure.
The only nominally republican I know of billionaire is Thiel, who committed the unpardonable sin of supporting Trump. And Trump isn't a doctronairre conservative by any means.
He's pro-gay marriage, but at least he is pro-life in his actions.
Even the "evil" Koch brothers are libertarians.
They are pro liberal causes, but their "sin" is that they support free markets.
I cannot think of another multi-billionaire who is any way "conservative".
