What is so alarming about a “gap between the rich and poor”?
To the Marxist, class-warfare mentality, it's not FAAAAAAAIIIIRRR!
The typical leftist definition of "fair" demands equality of outcome, regardless of any other factor(s). It's ironic to me that folks who believe this way are effectively begging to be rendered powerless. After all, if your personal risk, efforts and decisions have no effect on the outcome, then you have no power. And that's what these people apparently long for.
Sad,really.
The more important figure is income and wealth mobility. That's a proportional function of taxation, regulation and crony capitalism. All the Left’s “hate-the-rich” ire needs to be directed toward a mirror - they're creating a permanent underclass with their polices and giving cover to crony capitalists aka limousine liberals.
