The chart below, from the Economist [7], takes a look at how long it would take an individual from any given country to become a millionaire based on "how much the main breadwinner in an average household makes each year (before tax)." No major surprises here: the fastest spawning place for a budding millionaire, a term that has long ago lost its one-time cachet thanks to the world's central banks who have pumped some $14 trillion into the market, is the US, while those hoping to hit the vaunted seven figures in Bulgaria, Mexico and Romania would need to wait about 2-3 average lifetimes before they hit their monetary goal.
