The natural state of human society is anarchy. From the chaos of anarchy, rises a strong monarchical ruler to restore order. That strong king rules successfully for some time but is succeeded by weaker kings. The monarchy is then overtaken by an oligarchy led by aristocrats who are stronger and more savvy. This oligarchy is successful for some time until the oligarchy deteriorates due to weaker and less competent aristocrats gaining power. That leads to a populist uprising to overthrow the oligarchy, which can happen one of two ways: 1) electing a new strong monarch to take power, or 2) returning to anarchy (which will later require a strong leader to take power and restore order)... until the cycle repeats: anarchy to monarchy to oligarchy to anarchy to monarchy, etc... The same cycle is repeated in microcosms of other aspects of life: countries, corporations, organizations, or any type of group of humans.
Today's so-called civilized world is at the end of its development. It will fall just like the Roman Empire, which paid the price for its gluttony, laziness, disrespect for ordinary people, and love of easy gains.
In the end, a Germanic warrior appeared, who was uneducated, had no refined manners, and no other qualities of a Roman patrician, but he was strong, not lazy, and incredibly vital and resilient. And he chopped the lazy, fat Roman patrician into pieces. This is how Europe will fall as well. It will succumb to the uneducated but vital barbarians from the East and South.
