This essay is written in the classical tradition, making the classical assumption, and asking the classical question.
这个论题载于古典流派，做了经典的假设，亦提出了经典的问题。
The classics, from Smith to Marx, all assumed, or argued, that an unlimited supply of labour was available at subsistence wages.
从史密斯到马思都假设或是争论过这一经典：在给予维持最低生活工资时，劳动力是无限供给的。
They then enquired how production grows through time.
他们接着调查：随着时间过去下生产是怎样增长的。
They found the answer in capital accumulation, which they explained in terms of their analysis of the distribution of income.
他们根据收入分配的分析, 解释了这个问题的答案有关于资本积累。
Classical systems stems thus determined simultaneously income distribution and income growth, with the relative prices of commodities as a minor by-product.
古典系统的骨干(stems) 于是 同时决定 收入分配和收入增长 ，亦衍生出商品的相对价格(relative prices)。
