Ah, Paris in the Spring!
In City Journal, Theodore Dalrymple astounds with The Barbarians at the Gates of Paris:

But there is another growing, and much less reassuring, side to France. I go to Paris about four times a year and thus have a sense of the evolving preoccupations of the French middle classes. A few years ago it was schools: the much vaunted French educational system was falling apart; illiteracy was rising; children were leaving school as ignorant as they entered, and much worse-behaved. For the last couple of years, though, it has been crime: l?insécurité, les violences urbaines, les incivilités. Everyone has a tale to tell, and no dinner party is complete without a horrifying story. Every crime, one senses, means a vote for Le Pen or whoever replaces him.
...
Where does the increase in crime come from? The geographical answer: from the public housing projects that encircle and increasingly besiege every French city or town of any size, Paris especially. In these housing projects lives an immigrant population numbering several million, from North and West Africa mostly, along with their French-born descendants and a smattering of the least successful members of the French working class. From these projects, the excellence of the French public transport system ensures that the most fashionable arrondissements are within easy reach of the most inveterate thief and vandal.
...
But what is the problem to which these housing projects, known as cités, are the solution, conceived by serene and lucid minds like Le Corbusier?s? It is the problem of providing an Habitation de Loyer Modéré?a House at Moderate Rent, shortened to HLM?for the workers, largely immigrant, whom the factories needed during France?s great industrial expansion from the 1950s to the 1970s, when the unemployment rate was 2 percent and cheap labor was much in demand. By the late eighties, however, the demand had evaporated, but the people whose labor had satisfied it had not; and together with their descendants and a constant influx of new hopefuls, they made the provision of cheap housing more necessary than ever.

How long before there are cattle grazing in the Place Vendôme?
