《汉书·传·王贡两龚鲍传》
过去工匠不制造雕刻精美的器物，商人不流通奢侈浪费的货物，并非这些工匠和商人独具贤德，而是统治者政治教化的结果。
古者工不造雕王缘，商不通侈靡，非工商之独贤，政教使之然也。
In the past, craftsmen did not produce finely carved wares and merchants did not circulate extravagant and wasteful goods, not because these craftsmen and merchants were particularly virtuous, but because it was the result of the political teachings of the rulers.
