The degrading squabble over the level at which a nation still retaining some small capacity for shame will say "Below this wage, by irrefutable presumption, labor is uncompensated, ergo (implicitly) slavery", serves only to distract the working class, the surplus value of whose labor is being stolen, from the fact of the theft;
We need a maximum ratio by which the most highly compensated may command the compensation of multiples of their fellow humans.
Mondragon Co-op, the Basque industrial and commercial giant, sets 8.5 as the multiple that may separate the compensation of the highest executive and the lowest paid hourly employee.
Believe it or not, this order of magnitude was once at least approached in the United States.
That bastion of Calvinist Capitalism, Switzerland, regulates bankers wages.
Let's suppose that we tolerate three times Mondragon, and say that no income from an enterprise that has hourly employees may exceed, in all combined types of compensation (e.g. stock, low interest loans, what have you) 25X the compensation, without overtime, of the lowest hourly laborer in the company. You'd see the hourly rates rocket.
