Karl Marx was right about everything that he contributed to during his lifespan. Karl Marx stated that all of history is based on two types of people, the haves and the have-nots. The haves are rich people and the have-nots are poor people. If these two groups never existed in the first place why their be competition for housing, education, politics, food and other resources? Use your heads for once and think realistically for those of you who say Karl Marx was wrong. Wars and hunger also exist for the same reason, because there's competition worldwide. Wars are fought over religion, territory and resources. If there weren't separate classes of people in society then there wouldn't be wars over any of these things for people to become powerful in the first place. Nobody would feel entitled to territory or feel like their religion is superior or better than another person's religion to begin with. Hunger and famine also wouldn't happen either because only poor people go hungry and have nutrition problems and being poor is considered an economic class, the have-nots. Distribution also has a major role in economics because some resources have abundant and large quantities, but since people are greedy and selfish there isn't enough to go around for everyone. There's enough agriculture to feed everyone in this Earth, but humans use countless amounts of land for useless and pointless activities.
Karl Marx was correct in many assumptions and predictions. Humanity throughout human history has always been swinging to the left of the spectrum. You don't have to be communist, or even socialist to understand this principle. Evolutionary Socialism will lead to Communism. Marx and Engels were right about the world.
Capitalism is a form of slavery, in which those with money own labor from those who need money. The working class is always in need of money and thus must work their entire lives, without much choice about the matter. At some point the working class must stand up and demand greater equality. Karl Marx is right in many ways, though not without flaws
I think it is quite clear with all the economic troubles that besiege us today may suggest that Karl Marx might have predicted this. The working class seem to have a dimmer future than that of the capitalists and maybe it is because they have become so greedy that they just do not care.
People claim the working class is enslaved in the $7 minimum wage. This is false. If you want a higher paying job, go and get job skills and a education. Don't act like you deserve a lot of money for doing a job literally anyone can do. Equal rights =/= Equal pay. It's crazy how people feel entitled to everything. Nothing in life is free. A lot of rich people built their fortune from nothing.
