Answer:
Marx justifies his views on private property because he says the bourgeois classes have used their power to dispossess the working class and other disadvantaged people of property.
Step-by-step explanation:
For Marx, property is the product of a social relationship. It was the bourgeois notion of private property that he critiqued. The bourgeois had managed to gain enough power they could effectively dispossess others through legal codes. Marx was particularly focused on explaining the seizures of common lands in England for example to create large landowner farms, which is also similar to the way that Native American territories were appropriated by European settlers. For Marx, the working class was born out of the historical process that pushed them from their common land and denied any property rights so the bourgeois could become more powerful still.
