One way to compare would be to say that all of Norway could earn as much money, just sitting on ass all day, every day, as 3% (safe withdrawal rate) of Mexico, working 43 hours a week (actual stat from OECD). Alternately, compare to a country with lower GDP. "Norway (5.3M people) makes as much sitting on its investments as Latvia (2M people) earns working 36.5 hours per week." This has the advantage of comparing a Scandinavian country with a Baltic nation, with cultural and geographic proximity.
