It has to be the Central bankers, (global gov’t) day trading the entire global economy. Moving and rotating simulative lower valued currency values, country to country. Like “topping off” tanks around the world.
But they can’t win. Tax PAYER labor values are too low, like Corn being too low for a farmer. There is simply too much labor (bodies) and not enough work, to drive labor values higher.
The earlier powers that be (in the ’40s?) understood the need for a standard tax paying wage for entry level employees. Back at $1.25/hr the standard equaled 5 gallons of gas per hour.
