Earlier quoted context omitted.
I had a fellow American friend who lived in Bali for a year in the mid-70s. When he arrived, he shopped for his own food and cooked it. But he found that, since the merchants charged people by their social class, he could hire a housekeeper and have them buy and cook his food for the same price as buying his own found. And people expect him to do this.
Does the housekeeper pay less when s/he buys for her/himself ? Or does the seller asks the same price ? Wouldn't be in the housekeeper's interest to say he/she's buying for someone else, to cash in a bit extra ? Wouldn't it fit the seller ?
- The vendor charges every customer according to the customer's social class. A white guy pays through the nose. A servant-class local pays a modest amount. It doesn't matter who the food is supposed to be for.
- Thus, it is cheaper for the white guy to hire a housekeeper than to buy and prepare his own food. The white guy's food, if he has a housekeeper, will only cost as much as the housekeeper has to pay for food, because the housekeeper is responsible for buying it. And the savings relative to the white-guy price cover the housekeeper's wages.
