Karl Marx is the founder of modern communism. Bourgeousie defines the capitalists, those who own the means of production and who take advantage of the labor (work) of the proletariat (the mass of workers who do not own the means of production and are not fairly compensated for their work).
The statement that according to Marx, the best economic system would be one where the means of production and distribution are in the hands of the bourgeoisie is false. In contrast, according to Marx the best economic system would be one where the means of production and distribution are in the hands of the proleteriat.
