The limited nature of United States intervention in the economy and the Nacionalista Party's elite dominance of the Philippine political system ensured that the status quo in landlord and tenant relationships would be maintained, even if certain of its traditional aspects changed. A government attempt to establish homesteads modeled on those of the American West in 1903 did little to alter landholding arrangements. Although different regions of the archipelago had their own specific arrangements and different proportions of tenants and small proprietors, the kasama (sharecropper) system, was the most prevalent, particularly in the rice-growing areas of Central Luzon and the Visayan Islands.
Under this arrangement, the landowners supplied the seed and cash necessary to tide cultivators over during the planting season, whereas the cultivators provided tools and work animals and were responsible for one-half the expense of crop production. Usually, owner and sharecropper each took one-half of the harvest, although only after the former deducted a portion for expenses. Terms might be more liberal in frontier areas where owners needed to attract cultivators to clear the land. Sometimes land tenancy arrangements were three tiered. An original owner would lease land to an inquilino, who would then sublet it to kasamas. In the words of historian David R. Sturtevant: "Thrice removed from their proprietario, affected taos [peasants] received ever-diminishing shares from the picked-over remains of harvests."
Cultivators customarily were deep in debt, for they were dependent on advances made by the landowner or inquilino and had to pay steep interest rates. Principal and interest accumulated rapidly, becoming an impossible burden. It was estimated in 1924 that the average tenant family would have to labor uninterruptedly for 163 years to pay off debts and acquire title to the land they worked. The kasama system created a class of peons or serfs; children inherited the debts of their fathers, and over the generations families were tied in bondage to their estates. Contracts usually were unwritten, and landowners could change conditions to their own advantage.
Two factors led to a worsening of the cultivators' position. One was the rapid increase in the national population (from 7.6 million in 1905 to 16 million in 1939) brought about through improvements in public health, which put added pressure on the land, lowered the standard of living, and created a labor surplus. Closely tied to the population increase was the erosion of traditional patron-client ties. The landlord-tenant relationship was becoming more impersonal. The landlord's interest in the tenants' welfare was waning. Landlords ceased providing important services and used profits from the sale of cash crops to support their urban life-styles or to invest in other kinds of enterprises. Cultivators accused landowners of being shameless and forgetting the principle of utang na loob, demanding services from tenants without pay and giving nothing in return.
As the area under cultivation increased from 1.3 million hectares in 1903 to 4 million hectares in 1935--stimulated by United States demand for cash crops and by the growing population--tenancy also increased. In 1918 there were roughly 2 million farms, of which 1.5 million were operated by their owners; by 1939 these figures had declined to 1.6 million and 800,000, respectively, as individual proprietors became tenants or migrant laborers. Disparities in the distribution of wealth grew. By 1939 the wealthiest 10 percent of the population received 40 percent of the islands' income. The elite and the cultivators were separated culturally and geographically, as well as economically; as new urban centers rose, often with an Americanized culture, the elite left the countryside to become absentee landlords, leaving estate management in the hands of frequently abusive overseers. The Philippine Constabulary played a central role in suppressing antilandlord resistance.
