The report is saying that where you are born is the most predictive factor in determining how well you will do later in life, compared to other metrics.

By the way, how well do your theories on IQ and "genetic legacy" (nice dog-whistle) perform in combination with the actual data that shows pretty much every country in the world improving under almost every metric? Take Bangladesh now vs. 50 years ago for instance. Did the nation's "genetic legacy" magically improve over that time period?

Though I guess it must be easier to just attribute your situation to genetic superiority, rather than to theories supported by actual data.
