If it were night everywhere at the same time, this is what the Earth would look like (click to enlarge). But that strange statement doesn’t explain the importance of this view. What this image shows us is a representation of global wealth. As Vox puts it:
What you see is that in rich countries, light is largely a proxy for population density. Observe the thick cluster of the US Northeastern Megalopolis and the even bigger cluster in northwestern Europe. In poorer regions, however, the map represents not just population density but also the actual availability of electrical lighting. Huge swathes of Africa are barely illuminated at night, and densely populated India looks rather dim.
But of course, if it were night everywhere, that would mean the sun would be gone and we’d all be dead. Money can’t fix that.
It takes 14 minutes, but it boils down to the rich will always get richer and the rest of us better start tasting cat food now, because that’s all we’re going to be able to afford to eat when we retire.
The best evidence, in other words, is that the conventional wisdom is correct. Due to high unemployment and sluggish wage growth, lots of young people who aren’t in school don’t have very much money in their pockets. And yet even though young people have less money today, rents are higher and mortgage lending standards are tighter. Higher costs plus lower incomes = growing need to economize, so more people are living with their parents.
Not to mention, our old Kentucky home is so big, it makes sense for our son to be here, since the space he occupies is the equivalent of a studio apartment with its own kitchen and bathroom. I know this because my studio apartment in D.C. is smaller.
