It's interesting to consider Marx's viewpoint here, namely that businesses are always, even during good times, in a rigorous exploitation contest for the right to stay in business; and so only the businesses that use every possible means of exploiting their workers to the max, and thus piling up the biggest heap of surplus value as liquid assets; will be able to draw on pile that long enough to survive severe economic downturns (thus selecting for max exploitation over the longer run.) (Really a dollar auction, not that he used that phrase.) This seems esp poignant, and accurate, re low-wage and low-skill workers having to sign non-compete clauses. (Downturns were both more frequent and more severe in Marx's day.)

However I think Marx would be confounded by the Justice Department fully pushing this initiative, if indeed it does; since he believed the elites had an iron grip on democracies that was not going to be shaken. He would have predicted a far higher GINI than the (kinda high) one we have. More like Russia's, at least.

I may be selling him short though, he might view the Justice Dept action as mostly theatre; allowing other forms of exploitation to proceed apace and only addressing abusive clauses that weren't being enforced anyway; and the expansion of skilled and better-paid work in our day as only an apparent exception to his views.
