Do you know what this median annual household income of $71k means outside of the USA? Inequality is a global problem, unfortunately. Cheapest Tesla being generally affordable in one country doesn't mean it's not fairly expensive.
Side notes: - the World Inequality Database is full of interesting data (https://wid.world/) - I'm not sure the median income is always relevant (I mean, if half of a given population couldn't affort to eat correctly, I wouldn't say food is "generally affordable") - fortunately, not everybody needs a Tesla, let alone a car
