That is a stark claim with little empirical evidence. If you look at the world, you will find that Europe, one of the most affluent parts of the world has the lowest wealth inequality. While wealth inequality is very high in Africa, one of the poorer regions of the world.

Wealth inequality is far more likely to be the outcome of policies. Europe has been dominated more by various social democratic parties which have actively worked to reduce inequality. While areas such as North American with high levels of inequality has been dominated by parties pushing neoliberal economic policies.
