I am responding to the posts complaining about the “paltry” education of some hareidim.
1. Most are fluent or literate in four languages (two Germanic one, English and Yiddish, and to Semitic ones, Hebrew and Aramaic). They have at least sufficient math to function in the real world (probably not multidimensional calculus or quadratic equations or hexadecimal math, but do you really need those to run a store in Boro Park). While they lack basics of American business law or accounting, those are subjects not normally taught in high school, so the are no worse off than an American high school with a “Regents diploma” or the equivalent. Whereas the goyim used to concentrate on a “humanities” curriculum (strong on Greek and Latin, weak of practical skills such as math and science), they gave it up and it isn’t all clear if they are better off for it; hareidim still prefer the traditional Judaic humanities (modern Orthodox try to do both, at a high cost in money and in driving the kids crazy with overwork).
2. If you have a beard and pe’ot, do not dress “modern”, never eat in a treff restaurant (even if it serves a kosher item), and avoid secular work on all days during which secular work is prohibited – you can probably forget about 90% of the jobs for which a secular education prepares you. If you look at the CEO’s for the Fortune 500, or the Wall Street “brown shoe” law firms- you will find no one there who looks like you do. For all purposes arguing that Hareidim should prepare themselves for the well paying jobs in the secular economy is like telling Blacks under Jim Crow to prepare for careers in areas that never hired Blacks. For a career largely limited to work within Hareidi communities, the Hareidi humanities (non-scientific, non-vocational curriculum works fine); if you have doubts, note the housing costs in Boro Park or Williamsburg – if the theory that Hareidi education leave the child unable to function in a modern economy, those neighborhoods should have the cheapest housing in the region and that is simply not the case (the cheap areas are those inhabited by public school alumni whose educations left them unable to compete in the modern economy)
