The last chart I saw for the US showed numbers of STEM graduates increasing for immigrants, but decreasing for native/permres; and non-STEM unemployment was about double that for STEM. Is the over-production of non-STEM graduates decreasing? Is non-STEM unemployment going down? [Here I assume STEM is productive, or increasing productivity, and non-STEM is the pool for BS jobs and the elites - feel free to disagree]
