Back in 1546, the idiom first appeared in Proverbs, by John Heywood. This idiom is a metaphor referring to the notion that the buttered side of a piece of bread has more value than the plain side. It often denotes a situation that has an unequal dependency, such as a young trophy wife and her much older, wealthy husband. This metaphorical phrase stems from a time period in which many people were not as independent as they are in current times. Wives relied upon husbands, servants were dependent upon their wealthy employers, laborers and farmers were reliant upon landowners.

These situations often caused frustration and became untenable for the dependent. They would harbor thoughts of breaking the dependency—a wife leaving the marriage or having an affair, an employee resigning their position in a fit of pique. However, due consideration of which side their bread was buttered on, would usually take precedence over the desired state of freedom. Survival was a more compelling argument, and so the status quo would continue to be maintained.
