Very similar to multiculturalist Egypt where the new immigrants began looting the pyramids for valuables. Not my ancestors, why should I care? A society of atomic economic units with every man for himself. The dissolution of even the smallest bonds between strangers all dwelling in a strange land, each about to discover that every man is suspect as his enemy.
All these political ideas were inferior foreign imports, long demonstrated to be substandard notions for organizing a society and a nation. They have demonstrated their worthlessness many times over thousands of years. Man is not a learning animal and all it takes is a few generations for men to forget every single lesson of history and decline to the level of animals, completely amnesiac about their own past.
