Does the NBA need another expansion team?

I mean really...does the NBA need to have over 30 teams? I realize different cities want a franchise to root for, and to call their own... but is it me, or does this cheapen the quality of your average professional ball player? the NBA is supposed to be the ultimate level...made for the elite player only. these days we have overseas players coming in with no fear, and we can't even seem to win a gold medal anymore. if too many cooks can spoil the broth... the proverbial NBA broth is starting to taste like slop!
