Thomas Sowell on why England progressed faster than Ireland.

What is 19/20 th of the land own by england and 19/20th of the land worked by the Irish?

Lower IQ in those less developed countries ?

It's was easier to get to England from a Europe than it was to get to Ireland. Thus, they interacted more with other cultures and were exposed to different forms of technology.

this guy says makes sense

Sowell identifies prosperity and technological advancement with abstract, rather than concrete, thinking. And he notes that historically it's a minority mindset.
