Yes it seems odd.

Out sourcing construction jobs was great for the economy while leaving entire cities in rubbles.

But as soon as it hits the privileged class there is a call to "provide a specific replacement mechanism".

You mean manufacturing

Yes

Whose privilege are you sticking up for here in effect?

Math researchers are privileged class? I can guarantee - construction workers are extremely rich compared with math phds and most of postdocs. Talking about privileged class is absolutely laughable here.

I would bet that the parents of math PhDs are generally more privileged than the parents of construction workers.
