Yep. There's an informal name for people on a consulting or consulting team for this purpose: "talent". Interestingly, in women C-suite heavy environments, there is an occasional niche of bringing male talent on a team.

The general rule: Attractiveness correlates positively with income per unit effort. Attractive people get other people to do the hard work for them.

The corollary is that unattractive people must work harder, prove themselves more, and are forgiven less than attractive people. People tend to hold unconscious biases against unattractive people as more likely to be selfish, unkind, unworthy, and criminal.

PS: Respect to attractive people from well-to-do families who work their behinds off to not coast on stereotypical advantages.
