Of course, there are parents who send DC to state school and do all the extracurriculars privately. I know of a family that does this and DC does tennis, ballet, jazzdance, drama, flute, piano, karate... (and those are JUST the things I know of).
But this is a very, very time consuming process where you will desperately need a SAHM, and in the above case, said mom is driving from place to place for a good part of the day, summer camps, etc. - which all together would still cost a lot. In families where both parents work, this would prove impossible as there will be no one to chauffeur said kid around. To give their DCs the same opportunities, they will HAVE to go private. Private schools around us (we are spoilt for choice in the private sector, but DOOMED in the state sector) offer LOADS of extracurricular activities
However, should such parents be penalized by the wider MN community because they do so?
