As you suspect, we get a similar picture when looking at that in conjunction with the Gini coefficient and median income (and normalizing everything with PPP).

As you suspect, we get a similar picture when looking at that in conjunction with the Gini coefficient and median income (and normalizing everything with PPP). For example, Germany has an extremely low Gini of 28.3 (compare to the US at 47), and a relatively low median income of ~ $25K. This suggests that people are, uniformly, relatively poor (compared to counties like the US and UK). So, yes. $50K there would be pretty good.
