Here's some more oversimplification.

If you find a group of peasants better than local peasants at task X you can import them and the locals will either move to do task X elsewhere, accept lower salaries or switch to task Y.

Task Y can pay less and make a lot of pissed off cynics. Task Y may be harmful to society at large, like crime or Wall St quant voodoo. Wall St attracts quants because A students were promised respectable jobs, but because of STEM oversupply or whatever, many of those jobs pay 30K.

So you can't force one narrow interest, superior performance at task X, without consequences. Everything must be done in moderation, even it means inferior quality X. Task Y may destroy all the productivity gains of task X, like middle management, crashing economy for 3 years, etc.
