The increase in strikes in the United States is due to a mix of globalization and deglobalization processes, reversing trends from the past 20-25 years. Factors like technological progress and demographic shifts also play a role. The coronavirus pandemic has worsened relations between social classes, leading to demands for higher wages, better benefits, and streamlined management. Strikes are now more common in the service sector, reflecting a shift in the economy. This rise in strikes shows a growing divide between labor and capital in America, driven by political polarization.
