There is the greatest ever disparity between the wealthiest and poorest. But overall, people are better off. People are happiest however, when wealth is more even. Communist-style societies, in that regard, are better as everyone is kept within a similar level of wealth. But you wouldn't swap the UK now for Soviet Russia or life in communist Cuba. Yet we can learn from these societies. A greater focus on education, social provisions and the collective is often overlooked in our search for growth and extreme wealth.
Rather than get into an anti-globalisation narrative, shouldn't we focus on the extremely wealthy simply paying some tax - as a first step. They should have to give back a whole lot more. It doesn't have to just be money, could be more nuanced, providing mandatory investment in social enterprises etc.
