Why this site exists
Power is more than armies and money
The United States has about 4% of the world's people, yet it shapes much of how the rest of the world trades, communicates, travels, heals and entertains itself. That influence rests on six pillars, and each one has a long history and a set of numbers you can check.
This guide explains each pillar in plain language. It sources every figure, shows where the US leads and where it lags, and gives equal room to the critics. Read it in order, or jump to whatever interests you.
We shall nobly save, or meanly lose, the last best hope of earth.
