1. Technocrat vs Prole
The history of all hitherto existing society is the history of technical struggles.
Freeman and slave, patrician and plebian, lord and serf, guild-master  and journeyman, in a word, oppressor and oppressed, stood in constant opposition to one another, carried on an uninterrupted, now hidden, now open fight, a fight that each time ended, either in a revolutionary reconstitution of society at large, or in the common ruin of the contending classes.
In the earlier epochs of history, we find almost everywhere a complicated arrangement of society into various orders, a manifold gradation of social rank. In ancient Rome we have patricians, knights, plebians, slaves; in the Middle Ages, feudal lords, vassals, guild-masters, journeymen, apprentices, serfs; in almost all of these classes, again, subordinate gradations.
Too many times the dumb & stupid have ruled over the intelligent man, and this causes imbalances in society as cities become in-efficient, resources become scarce and costs increase.
