“if a job is that good for frum life, it will become saturated- not just with frum people but with people in general, because everyone wants a job like that.”
You can say that about any career. “If being a lawyer is such a good job, it will become saturated.” “If being a psychologist is such a good job, it will become saturated.” “If being a website developer is such a good job, it will become saturated.”
