GDP per person in history always blows my mind. In 1949, UK gdp/person was $11,000. Lower than Brazil now at $14K. $11K is right where Venezuela, Ecuador, and Bosnia are today.

Communist countries like the Soviet Union or Poland were at $3K. The level of Kenya, Syria, and Nepal today. $1K poorer than Bangladesh now which comes in at $4k per person.
