Wage Stagnation
The problem here is that the comparison is between <i>median</i> wages and <i>total</i> productivity, without demonstrating that the median worker is in any way responsible for the increased productivity.<p>If the median worker <i>isn't</i> responsible for the increased productivity,  are they entitled to a share of the work of other people?<p>I'm not necessarily saying they aren't, just that such an argument should be made explicitly.
