Second, customer-driven systems depoliticize the choice-of-provider decision. Even in competitive service delivery systems, public agencies usually contract with various providers (e.g., for training) or allocate budgets between various providers (e.g., between public colleges). Too often, politics interferes with these decisions. The providers with the largest constituencies get the most money, simply because they can bring the most political pressure to bear during budget time. Every college, every real estate developer, every large human service provider, has its constituency-many of which include heavyweight campaign contributors and workers. Few politicians get elected because service providers do a good job, but many politicians get defeated because a constituency rebels-so the politicians usually listen. But when the customers control the resources, no legislature can protect inferior providers from the verdicts rendered by those customers.
