With the occurrence of this fact, the worker would be doubly wronged, therefore beyond coexisting the high one of the prices of the agricultural products, also he would suffer with the low one from the wages. According to Ricardo, ' ' (…) the wages, while they will be regulated by the law of offers and the search, tend to lower, therefore the number of workers will continue to grow a little of what more quickly the search of the one hand-of-obra' '.

Observing the theories of Smith and of Ricardo we can perceive that Ricardo was well detalhista in the elaboration of its theory, therefore analyzed with profundidadea ordinance of culture lands, while Smith did not abide itself by these details. Leaving of this principle it is that it was more easy stops Ricardo to understand what it would happen with the taxes of profit of the producers with passing of the time, what Smith was not possible.
