Re: those of us left will earn more as a result
Brain drain vs. outsourcing Education?
How about this for a cynical thought: if we reduce our tech education output (they are more costly to run than yet another Estruscan Pottery / Sociology degree ) but have free movement of both student and labour, then we let other universities / countries fund the education and skim off the brightest to come back into the UK to apply those expensively-acquired skills. Seems like a historical policy that's now badly back-fired !
If we now block those freedoms of movement & we need to train up internally which means a massive re-investment in STEM from the ground up, which won't yield a sufficient number or quality of grads in just 2 years.
