ballet is the worst of worst (worse than cheer, modern dance that you can use on a school dance team, or competitive ballroom), at least for girls at the highest levels. Pointe shoes at $80 a pop for some mediocre ones that last less than a week. Summers at fancy academies in places like Scottsdale to break into professional and top college academies. Private lessons at $100 a pop. Costumes that can run in the hundreds of dollars. Makeup in the $1000s. Cut throat competition that you have very little control over depending on how you come out of the puberty lottery. Friends daughter is out to one of those academies this summer….my jaw hit the floor but one of the girls from the academy last year did make a lead dancer with the royal swedish ballet and won u18 euro fest. Your reward is a short ballet career and then you get to teach little kids.
