As part of his Labor Day message to workers in the United States, Sen. Bernie Sanders on Monday re-upped his call for the establishment of a 20% cut to the workweek with no loss in pay—an idea he said is “not radical” given the enormous productivity gains over recent decades that have resulted in massive profits for corporations but scraps for employees and the working class.
“It’s time for a 32-hour workweek with no loss in pay,” Sanders wrote in a Guardian op-ed as he cited a 480% increase in worker productivity since the 40-hour workweek was first established in 1940.
“It’s time,” he continued, “that working families were able to take advantage of the increased productivity that new technologies provide so that they can enjoy more leisure time, family time, educational and cultural opportunities—and less stress.”
TL;DR: Corruption and capitalism
Any kind of socialism (even relatively-speaking weak social democrats like Bernie) is severely underrepresented in US politics due to the influence of private money/capital in the government and in elections. The two party system/first past the post voting doesn’t help matters either.
The people with money actively want to supress socialism by any means necessary. Look at Joe McCarthy and the Red Scare if you want an example in US history that still affects us today.
Also Reagan with deregulation and Bill Clinton with “triangulation” (effectively becoming more economically right wing by finding the middle ground between right and left, while the right is constantly pushing right. See: the Ratchet Effect)
Bernie is one of the extremely few principled politicians who doesn’t take corporate money, but he also lacks power as he is one person.
