Since the “educational tax” came due shortly after harvest time, the easiest way for farmers to pay it was to sell a portion of their rice crop to the Chinese or Indian merchants who soon installed themselves in small towns across the country. However, harvest was when the market price of rice was, for obvious reasons, at its lowest; if one sold too much of one’s crop, that meant one would not have enough left to feed one’s family for the entire year, and thus be forced to buy one’s own rice back, on credit, from those same merchants later in the year when prices were much higher.
