I believe it’s because

1. The newer generations lack the experience and knowledge of oppression. Too long time has passes since the women in Russia gave their lives for the working class. Too long time has passed since families were ripped apart by the wave of capitalism that was induced by the Industrial Revolution. We have become complacent. You could draw a a parallel to how we have forgotten the price of democracy and that fact that democracy isn’t a constant or a permanent state of being once achieved, but something that has to be fought for continuously in various forms. The same goes for workers’ rights.
2. Capitalism is not merely a catalyst of racism, misogyny and otherization. It is also inherently detrimental to democracy, workers’ movements and a healthy climate in which one is allowed to find time and energy to meditate on the state of affairs, society, politics, workers’ rights and such. We are kept from sparing time and energy to organize and debate. Only monetary productivity remains. Only work is valued.
