Semantics. Words sometimes get in the way because of quibbling. Evil is still evil.
We do not examine the oligarchy nearly enough, we conservatives. That's because we're talking about multi-billionaires who we assume have earned their riches. Well, maybe they earned some of them. But mostly they make their money running the politicians who are the means to oppress the rest of us. Ex--Buffett claiming to love the planet when he stifles the fuel pipelines, when he really wants to make money on the rail transport.
Likewise, we are intent on proving "bias"--as if we can prosper with a well-reasoned argument. They just laugh at that. It's all about the money, and money is power and power is money.
