These three terms give rise to three distinct debates about the exact meaning of each term. A fourth debate concerns the fulfilment of the terms. When people argue about immigration, they often confuse the four debates, so that nobody understands what the argument is really about. It is therefore best to look at each of these debates separately.
Debate 1: The first clause of the immigration deal says simply that the host country allows immigrants in. But should this be understood as a duty or a favour? Is the host country obliged to open its gates to everybody, or does it have the right to pick and choose, and even to halt immigration altogether? Pro-immigrationists seem to think that countries have a moral duty to accept not just refugees, but also people from poverty-stricken lands who seek jobs and a better future. Especially in a globalised world, all humans have moral obligations towards all other humans, and those shirking these obligations are egoists or even racists.
In addition, many pro-immigrationists stress that it is impossible to completely stop immigration, and no matter how many walls and fences we build, desperate people will always find a way through. So it is better to legalise immigration and deal with it openly, than to create a vast underworld of human trafficking, illegal workers and paperless children.
Anti-immigrationists reply that if you use sufficient force, you can completely stop immigration, and except perhaps in the case of refugees fleeing brutal persecution in a neighbouring country, you are never obliged to open your door. Turkey may have a moral duty to allow desperate Syrian refugees to cross its border. But if these refugees then try to move on to Sweden, the Swedes are not bound to accept them. As for migrants who seek jobs and welfare, it is totally up to the host country whether it wants them in or not, and under what conditions.
Anti-immigrationists stress that one of the most basic rights of every human collective is to defend itself against invasion, whether in the form of armies or migrants. The Swedes have worked very hard and made numerous sacrifices in order to build a prosperous liberal democracy, and if the Syrians have failed to do the same, this is not the Swedes’ fault. If Swedish voters don’t want more Syrian immigrants in – for whatever reason – it is their right to refuse them entry. And if they do accept some immigrants, it should be absolutely clear that this is a favour Sweden extends rather than an obligation it fulfils. Which means that immigrants who are allowed into Sweden should feel extremely grateful for whatever they get, instead of coming with a list of demands as if they own the place.
Moreover, say the anti-immigrationists, a country can have whatever immigration policy it wants, screening immigrants not just for their criminal records or professional talents, but even for things like religion. If a country like Israel wants to allow in only Jews, and a country like Poland agrees to absorb Middle Eastern refugees on condition that they are Christians, this may seem distasteful, but it is perfectly within the rights of the Israeli or Polish voters.
What complicates matters is that in many cases people want to have their cake and eat it. Numerous countries turn a blind eye to illegal immigration, or even accept foreign workers on a temporary basis, because they want to benefit from the foreigners’ energy, talents and cheap labour. However, the countries then refuse to legalise the status of these people, saying that they don’t want immigration. In the long run, this could create hierarchical societies in which an upper class of full citizens exploits an underclass of powerless foreigners, as happens today in Qatar and several other Gulf States.
As long as this debate isn’t settled, it is extremely difficult to answer all subsequent questions about immigration. Since pro-immigrationists think that people have a right to immigrate to another land if they so wish, and host countries have a duty to absorb them, they react with moral outrage when people’s right to immigrate is violated, and when countries fail to perform their duty of absorption. Anti-immigrationists are astounded by such views. They see immigration as a privilege, and absorption as a favour. Why accuse people of being racists or fascists just because they refuse entry into their own country?
Of course, even if allowing immigrants in constitutes a favour rather than a duty, once the immigrants settle down the host country gradually incurs numerous duties towards them and their descendants. Thus you cannot justify anti-Semitism in the USA today by arguing that ‘we did your great-grandmother a favour by letting her into this country in 1910, so we can now treat you any way we like’.
