When I think about the crisis of our liberal system, I am reminded of an encounter almost 20 years ago in Berlin with Wolfgang Kartte, a former president of the German cartel office. I asked why he and his successors often took such a conservative view on competition cases and in particular why they were so dismissive of economic arguments.

Like the majority of economic policymakers in Germany, Kartte, who died in 2003, was a lawyer. He said he considered his job as helping the little guy to defend himself against the big guy. This was the job of a lawyer, not of an economist. Moreover, he said he was not interested in levelling the playing field, as the metaphor goes, but in tilting it in favour of the little guy.

The crisis of modern liberalism has similar elements. We have our own version of the little guy versus the big guy problem today — except that there is no one to tilt the field in the other direction. Smaller companies pay more taxes relative to their income than large multinational corporations. The economic policies that followed the financial crisis ended up widening income and wealth differences. Large immigration flows created insecurity, as did the arrival of new technologies. When you call voters deplorable — or patronise them, as happened in the UK after the Brexit vote — you add insult to injury.
