the context of this quote is that the UK economy shot itself in the foot by getting rid of cheap European labour, then someone responded actually no because they got even cheaper labour from outside Europe, I was pointing out that they are not cheap as they seem due to training cost and decline in quality of service.
They shot themselves in the foot already - but is there any proof that european labour was cheap? I kept reading about this, but my anecdata shows otherwise. At least in tech. In many cases it was the opposite tbh.
