I am often reminded of the photographs that my parents took of the process of sugar making, how the yoke of oxen go around and around in circles to activate the gear that crushes the sugar cane and grinds it into first molasses, then brown sugar, and then maybe, if refined further, white sugar. So that was used to illustrate the primitive living conditions that my parents first encountered in Central America, but of course that was in the 1960s. Probably they are much more advanced now, but still the photos don't lie. That was just how it was back then.
