Rabbi Dr Aaron Twerski writes in Crain's that the success some hareidim achieve in the business world proves that the education in hareidi schools is more than adequate to meet the needs of the secular world.
One can debate how many B&H Photo-like successes stories it takes to outweigh the many sad stories of hareidim who remain unemployed and unemployable due to lack of basic skills. However, I think R' Twerski's piece suffers from a more basic error: Education does not mean having a good job. There may be some correlation between the two, but they certainly are not identical.
If the entire purpose of education was to allow one to succeed in business, I would say we should end school at about sixth grade, or certainly by the end of elementary school. (Some of you, like me, may be old enough to remember Robert Fulghum's All I Really Need to Know I Learned in Kindergarten.) We should abolish algebra and trigonometry from the curriculum (it would certainly spare me my daughter's constant whining, "Why do we have to learn this?!") We should forget about challenging students to read Hamlet or Lear, to learn about other parts of the world, to discover something of past history, or to study other living creatures.
None of the above will help them run a business. None of the above are required to succeed at most professions. It will help them, however, appreciate their humanity, their past, the world around them. In other words, it will make them educated.
R' Twerski, this is what is lacking in the hareidi school system.
