The fact that most of what they consider problems cannot be solved is, to them, a feature not a bug. How much better off are black innercity families compared to the 1960s, now that we've fleeced generations unborn for the trillions of dollars spent on the Great Society? I don't know, because it seems to me every time there's an election we hear the same song and dance about poverty. It also seems that in the 1960s there was in fact such a thing as a "black innercity family". One of the biggest consequences of the Great Society is that the black family structure has been utterly decimated.
Why, it's almost as if it really has nothing to do with mitigating poverty and a lot more to do with reordering society as the Left sees fit. And what do you know, lo and behold, the "problem" is always just as bad as it was last year and the year before so therefore it's imperative that we keep giving up this and that.
Education is the same thing. It seems like every other year the local school system is pushing more education bonds. More, more, more. Always more, more, more. In almost any private endeavor, the demand for more, more, more will very quickly prompt the "what was accomplished with the last chunk of money you demanded?" question, but for some reason people treat public endeavors like they're immune to this line of questioning. Hell, to even ask the question means you want the poor chirren sitting at rickety desks under a leaky school roof, while their innocent little tummies rumble from emptiness.
All these pet causes of the Left are conveniently unsolvable, making them perfect vehicles for never ending moral grandstanding.
