Personal choice may have little to do with the indigenous background of ANY dance...
The most important point is this... the dances are and have been evolving to a point where they no longer reflect their beginnings ( you may like to know, that this type of discussion has been had at the highest levels ).
There are many in the higher echelons who are seeking a return to a more reflective nature of the genre.
As to music.....Remember this.. its the world of LATINOS that write 95% of all latin music.. they were around writing music ( and still are ) eons before the so called " latin dance music ", and trust me, they arent going anywhere !!
Lastly... the world of dance is NOT driven by the competitive arena ( its probably less than 5% of most schools teaching ) the social arena is what does, and has, always kept studios open, and the reality is.. we dont ( I hope ) promote the " show " style dance, that you seem to anchor your beliefs upon .
