Consider, for example, the police force. They are not customer (inasmuch as you can call the voter/taxpayer a customer) oriented force; they are a subjugation force. They carry sticks around, which they wield with gay abandon. Many of the forms of power in the current system are meant to keep the people down and subservient.
To continue this example: what we need are fewer state-level (where "state" is the region in question) police, and more local (city-level or district-level) police. We need more power on quality-of-life issues devolved to the local bodies, and less with the state or the feds.
The smaller the political unit, the more likely it is to be dominated by a clique of people. This can lead to corruption, but even in a non-corrupt setting it can lead to racist, casteist, or other kinds of discriminatory decisions about enforcement or resource allocation.
