An increase in real wages doesn't necessarily mean anything, as some of the most important investments in life have exploded in cost, far beyond adjustments for the inflation of currency--like housing.
So sure, you might be making a tad bit more, but everything is still VASTLY more expensive than it was.
It's impossible to limit costs in any meaningful way without causing production of actually important goods to implode, and honestly im 100% fine with some people making a percentage more than others (hey, if you're old, you want to live off the fruits of your labor, and probably transfer a portion of that income to your children), but measures have to be taken to ensure that the excesses of a few do not affect the basic comfort and dignity of everyone else (and frankly, I'm pretty sure there are actually enough resources and services to give everyone a GOOD life, not just an okay or dignified or basic one, but one full of ease and happiness).
At one point Warren Buffett was making nearly $40 million A DAY. I don't care if he is a saint, that kind of accumulation of wealth is a violation of the social contract. We agree to live peaceably in a society that is beneficial to everyone, but if a single person can just go around doing nothing (if he wanted to) and make that kind of money he should be considered an outlaw. It's a zero-sum game, you are literally TAKING THE WEALTH FROM OTHERS to give to yourself.
The growth of the economy means nothing, more money does not equate to more value for the average person when any given worker is only actually receiving a fraction of the worth of his work in the form of payment (after all, currency is ideally supposed to represent how much work you do and you are to be fairly compensated for your TIME).
Coupled with morally reprehensible land rights, banking systems, and taxes--it's some fucked up shit. Communism... doesn't work, it just doesn't. Karl Marx didn't know how to reach his utopia back then and we don't know how to reach it now, but there needs to be CONSIDERABLY more regulation in how wealth is distributed among the citizens of the world.

This chart is hella fucked up.
