Actual loyalty tends to get nugatory rewards: a week's extra holiday for 25 years of service?

真正的忠诚往往会得到没什么价值的奖励：任职25年能增加一周的？

Assuming flexible money-wages, the quantity of money as such is, indeed, nugatory in the long period; but the terms on which the monetary authority will change the quantity of money enters as a real determinant into the economic scheme.

设工资是灵活的，数量本身在长内确实是零的；但是当局改变数量的条件作为真正的决定因素进入了经济计划。
