By Devamrita SwamiKrishna explains in the Bhagavad Gita, as soon as there is lust there must be frustration, anger, there is no way around it because you are not the body, you are not the mind, your dedication to material desires must cause problems. So we can see that in the case of the phenomenon we are describing of the middle class being the ones who are shaking everything up, not the proletariats as Marx predicted, not the poverty stricken persons that we thought to be the constant source of trouble.
