Jobs, development and a broader political coalition

A larger Mexican army would keep more of the internal fighting in Mexican hands. Military jobs, railway construction, infrastructure and industry would also give more people a material interest in the government's survival. People with food, housing and money to spend would have something to lose if fighting continued. People who were cornered or had nothing left to lose would have fewer reasons to avoid desperate action. This is an interpretation of political incentives, rather than a guarantee that prosperity would end resistance. Movement toward constitutional monarchy could also attract liberals to a wider coalition.
