"Countries usually don’t knowingly commit economic suicide, but in Britain, millions seem ready to give it a try. On June 23, the United Kingdom will vote to decide whether to quit the European Union, the 28-nation economic bloc with a population of 508 million and a gross domestic product of almost $17 trillion. Let’s not be coy: Leaving the E.U. would be an act of national insanity.
It would weaken the U.K. economy, one of Europe’s strongest. The E.U. absorbs 44 percent of Britain’s exports; these might suffer because trade barriers, now virtually nonexistent between the U.K. and other E.U. members, would probably rise. Meanwhile, Britain would become less attractive as a production platform for the rest of Europe, so that new foreign direct investment in the U.K. — now $1.5 trillion — would fall.
Also threatened would be London’s status as Europe’s major financial center, home (for example) to 78 percent of E.U. foreign exchange trading. With the U.K. out of the E.U., some banking activities might move to Frankfurt or other cities. This would be a big blow."
