From Chapter V of An Inquiry into the Nature and Causes of the Wealth of Nations by Adam Smith:
Though the real value of a corn rent, it is to be observed, however, varies much less from century to century than that of a money rent, it varies much more from year to year. The money price of labour, as I shall endeavour to show hereafter, does not fluctuate from year to year with the money price of corn, but seems to be everywhere accommodated, not to the temporary or occasional, but to the average or ordinary price of that necessary of life.
What does he mean by "money price of labor"? Why did he say it's accommodated with average "price of that necessary of life"?
