For every destruction of a mass of productive forces in a financial crisis, and for every conquest of new markets and more thorough exploitation of old markets for capital expansion, bourgeoisie are digging its own grave.

Never Forget Class Struggle
Marx and Engels, two of the greatest classical social theorists, wrote: "The history of all hitherto existing society is the history of class struggles."
Bourgeoisie welcomes competition among the proletariat, because it helps extending working hours, reducing salaries, and lowering labour cost.
Poor working conditions and deliberately maintained unemployment will ultimately and ruthlessly exploit all members in society.
