《史记·七十列传·货殖列传》
普通百姓如农、工、商、贾，家有一万钱，每年利息可得二千钱，拥有一百万钱的人家，每年利息可得二十万，而更徭租赋的费用都从其中支出。
庶民农工商贾，率亦岁万息二千，百万之家则二十万，而更徭租赋出其中。
Ordinary people such as farmers, workers, businessmen, and merchants, with 10,000 coins, would earn 2,000 coins in annual interest, and those with 1 million coins would earn an annual interest of 200,000 coins, all of which would be spent on labor duty, tax, and rent.
