To some degree, there is a continuum. The world, especially Europe and the West, has still not recovered from the economic meltdown that followed 2008. It has cost many countries including the UK jobs, hopes and GDP growth. The political consequences of this are still playing out, and the Brexit vote was one example.
A lurch towards protectionism and a rise in nativist identity and sentiment - not necessarily xenophobia, as some commentators have insisted, that being a far more extreme and toxic emotion - has been apparent in many European countries, in the UK and frankly in the United States as well. As the US election campaign has shown us, the appetite for free trade is at a low. The persistent mess in the Middle East, with the resultant inflow of refugees to Europe, has only exacerbated matters.
