Purely economic points of view were also used to justify slavery. Many times with exactly the same arguments that are used for labour migration today.

I've heard your arguments time and time again, and sadly most people think like this. Even though any economic advantage of labour immigration is mostly reaped by big businesses.

A society has failed completely if it depends on abusing foreign labour to function. Let's not pretend that they are hiring the foreigners because it would be too expensive for them to hire locals of the quality they need. You can either side with the employers and think that this is great, or you could side with the people and think this is wrong.

I was born in a place were the school children are in the absolute top of the world in their knowledge as measured and awarded by Pisa. And I know from hiring local people, that the youth there are smart, hard working and honest. At the same time it is a place where the media together with politicians and businesses continuously blast out how there is a "shortage of competent labour" and that they need more immigrants. The truth is of course that they don't want to pay. I think it's just audacious to claim there is a shortage of competence, when there is nothing wrong with the stock material. There is a shortage of willingness to pay a decent salary for labour. And there is a fairly high amount of hatred from older generations towards younger generations. A hatred that I have never understood, but it is there out in the open.

Nobody has the right to cheap labour. If your business cannot turn a profit without paying lower than market rate salaries - you are simply a failure. You don't go demanding more immigrants so you can cut wages. You don't go demanding child labour so you can cut wages. You have to improve your business or admit that you are a failure and close shop.

No sympathy for businesses and sectors that cannot survive without abusing labour. They are not needed.

The talk about expensive education for native children is completely false, and just weird. Children are not expensive to educate anywhere in the world. Education turns expensive because corrupt practices of the governments that administrate education. The same government that then turns around and says the country needs more foreign labour because their own children are too expensive and incompetent.

Let's compare it with a farm. The owner of the farm notices that he can get more milk to sell by not letting the calves have any milk, letting them die instead. So soon he has no more cows and he goes on buying more cows from another farm. "Great! These cows start milking right away, no need to feed them for a year like I would have to with those annoying calfs"

And so on the farmer keeps milking his cows dry and just buying more from his neighbours. All the while people are complementing him for what an economic mastermind he is and how horrible those calfs where that were just drinking all his milk. That is the idea that has taken hold today.
