Since I never clarified what I meant and you came up with such a specific notion, it would appear you're projecting some defensiveness here.
But I will go ahead and clarify my position: The fact of the matter is, the US is a combative system. For it to work properly, each side has to take the extremes of their own position so the result ends up in the middle.
The rich don't need the poor or middle class to vote as a rich person, they can literally pay people to do that for them if they wish. A poor person should vote for issues that help them specifically and directly. Forget trickle-down even if you're ignorant enough to believe in it.
A perfect example is right-to-work states. Within the last year or so I read a story about a husband in (I believe it was) Kentucky who was sent out on a neglected platform to do some work, it collapsed and he died. The family was simply out a husband, father and provider. They couldn't even sue because the way the laws worked in that state meant the company would have literally had to try and murder the man for the family to be able to sue over the indecent.
I bet if you talked to most people in that state, they would be for this law because they don't want people suing McDonald's over hot coffee, for example. But why would they care? They're closer to the burned woman than they are McDonald's, voting their interests would mean they vote for the ability to sue McDonald's if they accidentally burn themselves.
Of course ditto-heads will scream "yea but if we did that it would ruin the whole country!" and indeed if the poor and middle class always got their way it would. But that wouldn't happen. Voting their own interests would simply pull the final result closer to the middle. That is, it would present ridiculous situations like a family not even being able to sue a company for a true case of near-criminal negligence and wrongful death.
