Maybe what is good for the individual isn't good for the community? In such cases, the individual behavior is characterized by the adjective "parasitic". If the dancers who learned skills through a given community are reluctant to nurture the younglings out of an obsession for a "fix", that seems to beg some serious questioning.
Parasitic is such a strong word - especially as i think that it is probably equally applicable to the "younglings". Why do they want to dance with experienced partners? what are they giving back? And in general i think we are not talking about beginners, we are talking about both leaders and followers who have between 2-3 years of experience, and who are stuck with the challenge that now that they have the basic technique down most dances are just not all that much fun, and the challenge becomes to change from being able to dance other peoples dance to dancing ones own dance.
I actually think what is not good for the community is the intermediate group of both followers and leaders who have given up on developing themselves and working on how they can create better dances for their partners, but (as leaders) stick with with the one or two partner that they know way too well or prey on beginners or (as followers) just want to "be danced" and entertained by the few leaders that are still able to present a technical challenge.
