The problem is that is hard to define/measure "richness" of a country. You can use monthly income or financial wealth as a metric, you have to decide between average and median etc. For example, in 2018, 45 single super-rich germans possessed the same amount of wealth as the poorest 50% of germans [0]. Using the median of distributed wealth would not express that, and if you cut off outliers by looking at percentiles and then averaging would also not express that.
