Another big gain for humanity in recent years has been the increase in freedom and democracy.
While slavery and human trafficking still exists in crime syndicates and the underworld, just 200 years ago it was legal in many countries. The global slave trade began shrinking when it was abolished in all British colonies 1834 and has since been made "formally banned everywhere," Norberg said.
Alongside the abolition of the slave trade, the world has become much more democratic. In 1900, no countries in the world gave each and every citizen one vote. Norberg writes:
"By 1950, the share of the world population living in democracies had increased from zero to thirty-one per cent, and by 2000, increased to fifty-eight per cent, according to Freedom House, the civil liberties watchdog."
