 Utilitarians face a greater problem than this theoretical one in determining what material distribution, or institutional structure, is prescribed by their theory. Those who share similar utilitarian theoretical principles frequently recommend very different distributions or structures to implement the principles. This problem occurs for other theories, with recommendations for distributions or economic structures to implement commonly varying among advocates with similar theoretical principles. But the advocates for other distributive principles tend to cluster significantly with respect to what they recommend. This is much less the case with respect to advocates for utilitarian and welfare-based distribution principles with advocates dispersed in their recommendations across the full range of possible distributions and economic structures. For instance, many preference utilitarians believe their principle prescribes strongly egalitarian structures with lots of state intervention while other preference utilitarians believe it prescribes a laissez faire style of capitalism.
