The reason is simple: growing public revulsion at a new class of super-rich who seem to be immune from the restraints that govern the lives of ordinary people. Senior bankers, private equity moguls and hedge fund managers appear cut off from the rest of us. They often pay little or no tax, increasingly live in heavily guarded enclaves, and some have little or no real allegiance to Britain. The sources of their wealth are often mysterious, and appear unrelated to merit. These feral rich pose, in their way, every bit as much of a danger to society as the rioters who stole and pillaged London streets last August.
