This time a post by Kevin O’Rouke on voxEU:
A glance at the electoral map suffices to confirm what earlier opinion polls had indicated: the Irish vote divided along class lines in a stark and disturbing fashion. In the most affluent constituencies of Dublin, such as Dun Laoghaire, where even a modest home can cost upwards of €1 million (although that is changing), 60% or more voted for the treaty. In working class areas of the city, it was the no vote which scored in excess of 60%. Brouard and Tiberj (2006) show that precisely the same division between rich and poor, or the skilled and unskilled, can be discerned in the French 2005 vote.
There are at least two ways of interpreting such [voting] patterns. The first would hold that well educated voters are more politically sophisticated and better able to understand the issues involved in a complex amendment to the institutional underpinnings of the European Union. The second interpretation is that, on the contrary, both rich and poor are capable of correctly discerning where their economic interests lie, and vote accordingly. The argument would be that globalisation generally, and European integration more narrowly, has overwhelmingly favoured skilled workers, at least in affluent countries such as France, Ireland and the Netherlands. Unskilled workers, by contrast, feel under threat from Romanian (or Asian) competition, or immigration from Eastern Europe and further afield. And while those of us who are more fortunate might regret it, it is hardly surprising that — in accordance with Heckscher-Ohlin logic — they vote accordingly.
As they say: Read the whole thing.
