They lie and say what they are doing is for the good of all Americans, but it is not. It is only for the rich, and to insure that they do not have to share their great wealth -- even though they earned it on the backs of many others. The rich want to control the government for their own benefit, and to the detriment of all other Americans. This would mean the end of democracy, and the birth of plutocracy -- and we are already well down that path.
Don't be fooled. Democracy and plutocracy are not the same thing -- not even close. Democracy is rule by the masses, while plutocracy is tyranny by the rich. The current Republican Party will not save this country, for they have bought into the trickle-down lies of the rich and have been pushing their agenda for them for decades now. The Democrats are our only hope right now to restore our democracy, but we must raise and voices and act to force them into doing it (for the plutocrats have bought some of them, too).
Do you want your democracy back? Or are you happy letting the rich rob you, steal your labor, and then tell you its for your own good? If you want to live in a democracy, then you must vote the GOP out of power -- at least until they come to their senses. And you must pressure Democrats to work for the good of all, not just the few. Those is the only choice we have (for no third party is going to ride in on a white horse and save us).
