Who benefited the least under a mercantile system?

Consumers were the ones who benefited the least under a mercantile system.

Explanation:

This is because Mercantilism, a system in which the states established commercial monopolies with their colonies, led to the distribution of relatively more expensive goods, since consumers were not free to import goods in places where they might be cheaper.

For this reason, mercantilism mainly benefited the political class, and a few producers and merchants who were closely linked with political power. The vast majority of people: the consumers, were affected because they had to pay for more expensive goods.
