@cicerone imposter,
You know who first proposed this idea that workers are unable to buy the
very thing they produce? Karl Marx.
How did that work out for the nations that tries to correct it? Well you decide.
I just gave you one reason why middle class are falling into poverty -- ACA. In addition, welfare and higher minimum wage will all contribute to middle class becoming poorer. Even your article says that: RISING COSTS. That's your key word here. Think about it, if that guy makes your daily essentials makes $15, how much would your toilet paper cost? Your bread and pretty everything else you depend on? Some people argues that would increase your "middle class wage" for the reason that minimum wage has gone up, is absolutely absurd. It's supply and demand once government is taken out of the equation.
CEOs and Officers are getting higher salaries because of supply and demand and there aren't that many out there. There's only one CEO of JPM and how many of those large conglomerate are there? You take every penny they make isn't going to help the middle class become any better.
Another key word here: production/nonsupervisory workers. What do you expect? Unskilled worker are easily replaceable, just like you aren't going to pay $5 more for the same toilet paper. Total Productivity did go up, because total factor of productivity, i.e. technology has increased. You need to study some economics my friend. Take CFA level 1, you'll see what I mean. I blame everything on liberals because there are only two kinds of them: 1. ignorant of the laws of economics. 2. hypocrites who preys on other's ignorance for power and status. Jill Stein falls in the 2nd category.
