Really? Because contrary to current dogma, the bulk of human history has had "haves" and "have nots" - and the disparity between the two has been STAGGERING.
The fact is that neo-socialists (and people who derive political power from such positions - let's not forget the original mission of the AFL-CIO quoted in the OP) have as just an illusionary utopianist view of "what society should be" with as much rationale as do the Tea-Partiers.
The fact is that some people are capable, some aren't.
Take a mythical cross-section community of the population, say 100 people, give them all $50,000.
At the end of a year, there's going to be a bell curve of results.
A small proportion are going to hold most of the money.
The bulk middle of the population, the majority, will have more or less held onto theirs.
A small proportion will have blown it all and have nothing.
Witness: the bulk of lottery winners are eventually poorer than when they started. This is PROOF that simply throwing money at poor people is truly a stupid idea - it doesn't help.
You cannot legislate away people's inherently bad choices, and I would argue it's IMMORAL* to do so. The US has, in my view, a larger and more visible poor underclass because there are indeed fewer protections against peoples' bad decisions. I agree there is a need for a social safety net to help the unfortunate - that's what a society does. But ultimately, people need to face the consequences of their own bad choices or someone else will have to bear that cost.
Had a baby at 14? You're an idiot, and get to work in a crappy minimum-skill job forever. Fathered that baby? You NEED to be responsible for the financial well-being of that mother and child until the kids' 18, or the state should drag that value out of you in a workhouse or penal battalion. Committed a crime? You're a selfish idiot who gets to work in low-wage jobs because you've proven you don't have fundamental self control that most people are able to display.
I believe second-chances are earned; nobody's entitled to them.
*this will of course only make sense to people who treat every human equally; much is made of people 'dehumanizing' the poor, but in my experience there is an equal segment of the population who don't consider the wealthy worthy of any sort of moral consideration, solely because of their wealth.
