US: 18.5 Norway: 6.5
The ratio of the average income of the richest 10% to the poorest 10%
From wikipedia [1]:
The petroleum industry accounts for around a quarter of the country's gross domestic product (GDP).On a per-capita basis, Norway is the world's largest producer of oil and natural gas outside of the Middle East.
Now I realize that you were probably just saying that Norway and US are comparable in terms of GDP per capita. Am I correct?
You can of course get semi-anonymity by paying someone else to perform the search for you, but it's not really done much. Companies are generally nicer in Norway anyway, likely due to our lack of minimum wage, CLAs and tripartite cooperation model.
More states are implementing laws so prospective employers cannot ask or base a salary offer on prior wages. This should positively effect gender and racial inequality at least during hiring. This would render all that protection moot.
