This is a difficult problem to solve for a society though. The army is needed, because it’s what allows your country to exist. In time of peace, draft is really not optimal, because people are taken a year of their life for absolutely nothing. But the army need to keep its structure alive and functioning, or there’ll be nothing when it’s needed.

The army of professionals is a good solution, and they do a hard job to keep an important piece of the state alive when no one cares about it.

Ultimately I think it’s better if poor people make the core of the army because it means ultimately the safety of the nation is in their hands. Still, culture of the military men should be better taken care of, and elitism of the command structure should be fought.
