In the early 19 century Peruvians had the opportunity «to make money» in the same way as the thousands of foreigners who arrived in our country for that purpose. Those men followed two different paths to achieve fortune and a new social status in 19 th th century Peru: the opportunistic and mercenary use of the State mechanisms, and the «modern» implementation of responsible and creative work, savings, investment, reinvestment, education, compliance of law, giving value to time, living frugally and other modern ideas.
