Nicaragua's informal sector workers include tinsmiths, mattress makers, seamstresses, bakers, shoemakers, and carpenters; people who take in laundry and ironing or prepare food for sale in the streets; and thousands of peddlers, owners of small businesses (often operating out of their own homes), and market stall operators. Some work alone, but others labor in the small talleres (workshops/factories) that are responsible for a large share of the country's industrial production. Because informal sector earnings are generally very low, few families can subsist on one income.Original source:  Like most Latin American nations Nicaragua is also characterized by a very small upper-class, roughly 2% of the population, that is very wealthy and wields the political and economic power in the country that is not in the hands of foreign corporations and private industries. These families are oligarchical in nature and have ruled Nicaragua for generations and their wealth is politically and economically horizontally and vertically integrated.
