Cal Tech and MIT still have tenured professors who resist this grade inflation.

MIT still is admitting roughly twice the freshman class size,
and “washing out” engineering students with challenging introductory classes.

In the old days these washed out MIT first year students enrolled in other universities for their 2nd year,
but today many transfer to the non-science, low math skill majors added to MIT in recent decades.

India and mainland China copied the old MIT freshman “weed out” tradition at their tech institutes,
which remain grueling.
Notice all the Indian tech university graduates near the top of USA and UK companies?
