Not only that, but we should remember that there are simply more _people_ globally. Using the U.S. as an example - when my dad was born in 1954, the U.S. population was HALF of what it is now. Should we assume that all markets and wage/labor share increase linearly AND directly (in time) with population? Certainly not.

Somewhat tangential, this population factor also plays a major role (though not the only one) for the reason city or near-city housing prices have skyrocketed - building construction just didn't keep up with the sheer population growth in many advanced economies, even more so in cities of advanced economies. This is why my buddy in Palo Alto is, for all intents and purposes, forced to live with two retirees and 4 other Millenial devs to afford rent.
