This is why the J visas were widened from "cultural exchange" to employment of foreign people (mostly students) at amusement parks, resorts, and now at factories... and then to bring in foreign doctors for "underserved" rural areas, which, in practice, has turned into urban areas within blocks of major hospitals. It's all about driving down compensation, increasing hours and generally worsening working conditions... the same as for H-1B and L and F with OPT visas.
