What Booman said (here’s a taste; go read the whole thing):
Look, this isn’t complicated. There are a few very wealthy people in this country and there are hundreds of millions of…well…everyone else. Very wealthy people have a particular set of concerns. They would like to keep the money they have and they’d like to set the optimal conditions for them to make much more money. In this, they’re not really much different than the rest of us, but their behavior can have an outsized impact on all kinds of things, like the integrity of investments or the quality and safety of products or the healthiness of the air and water or the kind of compensation we receive as their employees. Very frequently, our interests conflict with their interests. They’re badly outnumbered, so they should expect to lose political arguments pretty much all the time. But they have money. Lots and lots of money. And they use that money to create political speech and political outcomes. But speech isn’t enough. They need votes. And the only way for them to get enough votes to have their interests reach parity with ours is to align themselves with some other large segment of the population. In our recent history, this has been religious conservatives and, especially, Southerners who still retain an unhealthy contempt for the Federal government that beat them in the Civil War. There’s also another group of people, usually called libertarians, who are basically cheerleaders for rich fat cats not out of any particular self-interest but probably as a result of some quirky protein produced by their DNA in utero. Who knows what is wrong with these people? Most of them were born on third base, think they hit a triple, and are really pissed that they haven’t yet scored. They blame empathy. And Al Sharpton.
