Did karl max believe that the poor deserve to be on the bottom of the food chain

I doubt it, because Marxism is the basis of what is now known as Communism. They're political ideologies that mainly focus on erasing all social hierarchies, so a person who is poor is equal to a person who is rich (well, technically there would be no poor or rich people because everyone would have the same income). So, no, Marx would not believe anyone deserves to be at the bottom because that was not his way of thinking.

no one should discriminated against because he or she is not from a minority group
