Who pays those "punitive charges" that negate the enhanced corporate profits that have come from offshoring?
Tariffs are regressive sales taxes falling mainly on working-class and retired Americans including millions of workers who lost their jobs to offshoring.
Trump's "Hail Mary" tariffs confirm what Marx wrote about the final stages of capitalism:
The Economics of a Dying Empire (w/ Richard Wolff) | The Chris Hedges Report
"Unable to expand and generate profits at past levels, the capitalist system will begin to consume the structures that sustain it.
"It will prey upon, in the name of austerity and government efficiency, the working class and the poor, driving them ever deeper into debt and poverty and diminishing the capacity of the state to serve the needs of ordinary citizens."
