To bring it into one of many human examples I personally have decades of witnessing, is an aunt & uncle who would be considered the "power couple" of the family. Wealth, education, status, all far outshines the rest of the extended family. But depending on when you witness them, they would be classed power couple, conservative-traditional couple, or egalitarian/50-50 type.
