If it were in Alfheim, idealistic young people could join the military, work, or become political agitators to find a way out. But in Charlemagne, it's not the case.
Unlike the conditions relied upon by Alfheim to establish a preliminary modern government and army, the appointment of senior commanders in the Charlemagne Army was not based on merit but on noble birth or nepotism.
Those with strong characters and an independent spirit not only fail to gain promotion in the Charlemagne Army, but are also ostracized. In peacetime, such people are seen by their superiors as unruly and difficult to get along with, and have unfavorable remarks left in their files. Over time, talented individuals who fail to get promoted often choose to leave the military. What remains are mostly weaklings, disappointments, and fools who obediently follow orders.
