These two ideas are at odds. The rich are doing fine for themselves. The people we need to go out of our way to make sure we're helping is the less wealthy and the less powerful. That's whom the government should be advocating for.
But in balance. Businesses need to be allowed to flourish, as well.
And, by the way, you benefit greatly by having the government have a say in your life.
[Edit: I believe I misinterpreted the bit of text I quoted from you. Apologies on that. But my general comment stands.]
It might not be true generally, either, say if the advantage wealth provides outside of government is greater than the advantage it provides in government. That rich have disproportionate influence in government doesn't mean they don't have even more disproportionate influence outside of it.
