The summer solstice occurs in the northern hemisphere when the sun is at the most acute angle above the horizon. It usually occurs on or about June 21.
North Korea's economy is in a dire state. Analysts estimate per capita income is $1,000-$2,000 (Â£640-Â£1,280) per year. Compare that with South Korea, where per capita income is almost $20,000. That means that even at the higher end of the range, North Koreans make just 10% of what their average southern counterparts make. One estimate says it works out to about $4 a day. However, information coming out of North Korea is very unreliable and so the numbers could be much worse.
South Koreaâs employment structure requires workers to work long hours despite low productivity, as it is more cost-effective for businesses,â Kim Jong-jin, a researcher from the Korea Labor & Society Institute, told The Korea Herald. According to OECD data, South Koreansâ labor productivity was $31.90 per hour in 2014, much lower than the OECD average of $49. It draws a stark comparison with France, where laborers work for 35 hours a week, but with productivity scores of $64 per hour.
