Sometimes the counter-intuitive allows you to open your mind and see through to alternative goals and pathways. Perhaps to understand how to save something you figure out the best way to destroy it. Then do the opposite. What I find interesting about this list from Reg Adkins at Life Hack is that applies quite nicely regardless of the size of your community.
Provide subsidies which retard the natural evolution of the local economy.
Migrate all governmental authority to locations distant from the community.
Siphon off any gifted community leaders into the larger government body.
Train residents to rely on outside parties for leadership and guidance.
Centralize manufacturing to the extinction the local craftsman/artisan.
Through lending practices create an undesirable local market.
Draw as many wage earning males out of the community as possible.
Encourage inflation by the steady increase in wage earning at the lowest level.
Encourage lower paying service industry development over manufacturing.
Allow a build up of substandard, low cost housing to corral the poor in one area.
