This is absolutely correct. People who are genuinely forced to flee by persecution are generally better educated than average, and they are a long term loss to their source country.
Most economic migrants are fleeing because they are illiterate, innumerate, have no qualifications, and have no chance of a job in their own country. So they are also mostly completely useless to European societies. Any migrant from these countries (particularly African countries) who is sufficiently educated, honest, literate and numerate to make any sort of contribution in Europe should be automatically returned to their home country where they are in great shortage. I think unemployment in Nigeria is about 40% - but having worked there for many years it is also very difficult to recruit competent and honest locals to fill even mildly technical positions. There is simultaneously mass unemployment and labour shortages in a lot of Africa.
