Quite simply, anyone who disagrees with the concept of those well off assisting those worse off, for the various reasons including:
-Without them, your wealth is for naught. Where did you think you got that money from huh? Magic land? It's *their* inherent wealth you harvested, you are obliged to help them. It's both right, and inherently human.
-Without proper transferal of wealth, a purely capitalistic system will eventually die. Yep, this is because, again, wealth is inherently limited. There's only so much in the world, in your country, etc. Eventually, all of the wealth will collect at the top, and the system will simply stop working, as there is nothing to move the market anymore.
-In a capitalist economy, unchecked capitalism will lead to an ever larger underclass, to, eventually, a mind boggling split between those who have, and those who have not. Very simply, there will be lords, born into ruling and never having to work for it, the staggering mass of their families fortune pushing their agenda and power along. Intriguingly it will lead to that which capitalism was supposed to avoid, an elitist system where the individual is not entitled to the sweat of their brow (bonus points for who I got that from). The other major problem is this will cause social and political unrest once the connection has been made that the dream has died.
Anyway, as I was saying. People who do not support socialism in some form, due to any of the above reasons, and many more, are either stupid, indoctrinated as hell by those with the wealth (yes, that's what I call most of you lower and middle class right wing Americans, willing slaves, like to the Reapers), or you have an agenda, one that does not happen to support the greater good.
The solution is simple. You should be educated, by the book or by the sword.
That's my two cents. I get good mileage for words
