"Most likely...The correlation between vast wealth accruing to a tiny elite and the ability of people to move between the rest of the rungs of the income ladder may be small—at least for now."

And there's the crux of the matter. Even if that correlation remains small, the top rung of that ladder is so far out of reach of everyone else, -and- incorporates an insanely disproportionate amount of money, power, and influence, that it will likely remain forever out of reach, while allowing for policies that markedly worsen the lives of those on lower rungs.
