Civilian careers, service motivation, and Western recruitment

Why do Western armed forces face recruitment difficulties when some developing countries do not?

Civilian careers compete on pay, stability, and advancement, while service motivation, technical entry requirements, and restrictive eligibility rules also affect who joins.

Stable civilian wages and opportunities for advancement reduce the material incentive to enlist. A visible threat and a convincing purpose for service can pull in the opposite direction. The criticism of restrictive entry standards is that systems designed for small wars of choice can exclude willing applicants even when recruiting is difficult. Increasing technical demands also bring armed forces into competition for people who already have attractive civilian careers. The later RNVR example connects that manpower problem to the value of keeping experienced civilian mariners involved before wartime expansion.
