The current value for a kg of gold is just over 93,000 USD which is comparable to the median wealth of people living in the Republic of Ireland (median wealth of $95,872). It essentially puts you in the top 25 wealthiest nations in the world as far as I can tell
Average in the context of wealthy industrialized nations, but globally not even close to median. I went with median over average as well because there are far more impoverished people globally than there are wealthy, and on the other end the wealthy are often wealth hoarding at an insane rate. Median values help minimize the impact of extreme outliers
