Signalling Status plays a big role in group formation/group maintenance/social cohesion etc.
The larger groups grow, the more complex the group dynamics get, keeping groups of people together and preventing them from disintegrating is one of the most complex problem we face, given all the differences in culture, religion, language, class, personalities, ambitions, values, needs, intelligence, skill, education level, interests etc etc
A short cut frequently used (cause its easy) is using Leisure and Luxury (see Theory of the Leisure Class).
"So you like what I wear, where I stay, what I eat, who my friends are, what toys I have and want to be like me or hang out with me then do what I say". This works pretty well. In fact Veblen's prediction in Theory of the Leisure Class was that since Tech has a tendency to eliminate waste, tech would eventually eliminate the need for a Leisure/Status signalling Class that keeps large groups from unraveling.
But social cohesion of large groups is such a complex problem, society even today requires all kinds of Status Signalling to keep the groups together.
If you find ways to keep groups together without status signalling you are onto something special.
