Whether it’s in economics, politics, or wider society, there’s a debate about capitalism versus socialism; but I don’t really think that’s what’s happening. If you look at the populist undercurrents around the world- it’s really about walls & bridges. When there are big changes in the economy – like globalisation or technological change, the simple thing to tell voters is, ‘we’ll build a wall to protect you against those changes…’ what you really need however, is bridges.
