ANSWER QUICKLY OMG What did Karl Marx and Engels predict would happen as a result of uneven distribution of wealth(large gap between the rich and poor)? He did not care about it

Class struggle and ultimately revolution were at the center of Marx and Engels' ideas about the distribution of wealth in society.  

Explanation:

Marx and Engels predicted that there would eventually be a class struggle between the rich and the poor because the poor become alienated from the results of their labor and the rich or bourgeoisie begin to monopolize more of the means of production for their own benefit. Their vision of the outcome of this struggle boils down to the following quote from The Communist Manifesto, "the forces of production which develop in the midst of bourgeois society create at the same time the material conditions for resolving this contradiction. With this social development the prehistory of human society ends."  The "material conditions" mentioned in the quote above are the awareness of the laborers that they are being exploited and they will eventually engage in a revolution against the bourgeoisie in this view.  Remember that historically the word communism in Marx and Engels' time did not have all the historical and ideological baggage it has today.
