Wealth and wealth inequality: What accounts for these developments?

We look at the situations of the United States, the euro zone and France. In the long term, there has been an increase in wealth in relation to income and a rise in wealth inequality. What accounts for these developments? Not additional savings or increased capital intensity (there could be an increase in wealth if economic agents saved more to accumulate more capital, but this is not the case); The rise in the prices of certain assets (equities, real estate) relative to goods prices, and the fact that these assets whose relative prices are rising are primarily held by households with the highest income and wealth; And, all things considered, the increasingly expansionary monetary policies that have led to higher asset prices and also higher corporate profitability that has increased the value of equities. It is these two developments that must be corrected if we want to stabilise wealth inequality.
