Yeah, and you are clearly not listening. NO ONE has proposed a truly flat tax where they guy who makes $1 pays x% and the guy who makes $1,000,000 also pays x%. Read back a few pages, ok?
That said, your argument for a progressive tax (if I may indulge in a straw man) is that "people who make less have to live on less."
Well, duh. Yes. That's actually how it works!
Regarding the rest- yes, I agree that both parties are beholden to them what hold the purse strings. DOWN WITH CITIZENS UNITED! (You see why I keep saying that'd fix everything?) But IMO the Republicans are far more the "party of the corporations" than are the Democrats. If nothing else, the Republicans would raze our national forests, drill in our national parks, and tax us to give subsidies to Exxon, whereas that is not generally the Democrat plan. This is one big area where I trip up with the Republicans and why, as I have said, that though I think I actually trend conservative on most things I've voted Democrat recently. I guess I just have that much of a populist streak.
