Excluded from the transit area, the farmers of the interior developed a system of non-commodity production. The historical conditions of a small, dispersed rural population using simple productive techniques, having relatively easy access to raw materials, and transmitting few goods to the cities led in the countryside to a system of production for immediate consumption. Huddled in small domestic units, the campesinos have through the years produced primarily to meet their own needs and not to augment their wealth. This fundamental orientation - household production for household consumption - is reflected directly in the people's ideology. Production for livelihood, however, does not exclude producing a surplus; the enigma of production for use is not whether a surplus is produced but why the surplus which is produced does not accumulate and transform the system.
