Any mention I have seen of a "power couple" is always catering to the ego of women. No man cares about power couples, because they are not looking for a woman who is chasing some high flying career.

It only seeks to validate the feminist idea that a women should be celebrated for chasing careers, and that they should be rewarded for keeping their hypergamy even when it is unnecessary. A family can be supported fully with one high flying career. Two of them just means more money than needed.
