Given that neoliberalism and capitalism are virtually the same thing, I would argue that this poll means just the opposite of what you think it does. The referendum was a closely fought rejection of the economic outcomes of several decades of neoliberal policy.

Social wedge issues are important politically, but Brexit was really about the failures of globalized capitalism and governments to cope. If there were plenty of stable jobs with generous benefits and pensions, or if public services were adequate, there would never have been any real urge to Leave.
