When she isn’t shipping in more Syrian refugees, or trying to find new ways to destroy the Greek economy, the German Chancellor Angela Merkel is fond of quoting an alarming statistic: Europe accounts for just 7pc of the world’s population, and 25pc of its GDP, and yet it also accounts for a massive 50pc of its welfare spending.

The point is an important one. Europe’s welfare spending is out of control, and is on a scale that is both lavish and unaffordable compared with the rest of the world. There is a problem, however. Neither she, nor any other political leader in Europe, has the will to do anything about it.

Eurostat, the statistical agency of the European Union, has this week published updated figures on the total welfare bill across Europe. It is rising, and in some countries is getting up to a quarter of national output. Meanwhile, the percentage of spending on stuff like infrastructure or education, which increase an economy’s potential output, is falling.
