The gubmint was about to collapse in the 1920's due to the failures of capitalism, so the keynesians took power and make concessions to the working class to prevent a proletrian revolution. Inspired from the one that occured in the Russian Empire. This was called the New Deal and was orchestrated by the fascistic FDR. They used Chile as an experiment to see if they could do neoliberalism. Eventually, organized labor fell off and they realized that they didn't need to uphold those concessions anymore as the situation improved. NEOLIBERALSIM!!!!! And all the gains the working class made in the 20th century were eroded and that's why reformism can never work as the bourgeoisie will take any chance to ack us etc. etc.
