1. You don’t start as a manager (unless its a family owned business).
2. From a “frum” perspective, the same issues in a B.A. or B.S. arise in getting an associate’s degree, or even a training program at a college. Most of the problems for frum people also arise in a non-academic apprenticeship program if it is one run by and primarily serving goyim. Most of the jobs listed in the first posting require some form of academic training, or some form of apprenticeship – which are not available within our community.
3. With no formal academic training outside of yeshiva/seminary, one can often get an entry level job in the medical field (as an assistant to an assistant doing jobs professionals refuse to do – such as helping people use the bathroom). Retailing at the lowest level is usually an open field, and if you are good, you can rise (think Walmart’s, or a pushcart operator growing the business into a major chain) . The military requires no training or experience. Almost all the jobs taken by illegal immigrants since American citizens refuse to do them can be taken by anyone who has no training (manual labor, food service, gardening, house cleaning, child care).
4. If you don’t like the idea of going to “college” (or any other goyish school or trainng program), you probably don’t want to work with and for goyim. That usually means working solely within the Jewish community. In return for low pay, you don’t have to worry about Shabbos, Kashrut or being in an environmnt with widespread dubious sexual behaviors (some of which are illegal, some not). For much of the frum community, the hassles of working for the goyim aren’t worth the money.
