1. Any accredited bachelor’s degree opens doors, though one usually has to have job skills to walk through.
2. Often (e.g. for federal civil service) a list of classes and acquired job skills is just as good.
3. If one desires to enter a graduate program, universities tend to insist on a bachelors, so the “BTL” is useful as long as you took the right classes for the program (distance education is an option to have the necessary classes, for medical school many schools offer “make up” programs for someone with a non-premed background and a bachelors who wants to go to medical school).
4. There are plenty of blue collar jobs that don’t require a bachelors that few frum Jews have shown interest in (e.g. a tool and dye maker).
