Physical Wealth
Luke 16:9-13 No servant can serve two masters: for either he will hate the one, and love the other; or else he will hold to the one, and despise the other. You cannot serve God (the Father) and Mammon.
(i.e. the Big Mama, a word apparently first recorded around Jesus's era as the personification of riches)
In 2019, a brief summary of regions with liquid assets and liabilities – a very, very rough picture 
Allianz
This table (click here for a full list of countries) is based on each region's gross financial household assets measured in euros by Allianz – currency stocks and bonds at current market values, with a separate column for debt, including mortgage debt. Total gross assets equals €172 trillion. Nett assets €130 trillion.
Its list of countries does not include Africa or the Middle East (other than Turkey, Israel and South Africa).
In Australia perhaps 90% of total debt is property loans, however current house and land values are not included in Gross Assets.
