EL PAÍS visits four of the towns with the highest per capita income in Spain. From the payment of the taxi to the ambulatory to 2,000 euros per self-employed, they offer services to their neighbors that are unimaginable for other similar municipalities.

Governing the bonanza is simpler than misery. The mayors of Spanish towns that are home to wind, solar, hydroelectric or nuclear power plants know this, with buoyant budgets that allow them to build and subsidize neighbors.
