If I ask you to write down the last 4 digits of your social security number, and then take you out to lunch and ask you how many dentists there are in Manhattan, there's going to be a high correlation between those two numbers. What happens is that the number psychologically makes you feel confident.
In the United States, one of the main topics of academic political science is the study of attitudes and policy and their correlation. The study of attitudes is reasonably easy in the United States: heavily-polled society, pretty serious and accurate polls, and policy you can see, and you can compare them.
The correlation between poverty and obesity can be traced to agricultural policies and subsidies.

There is a correlation between economic inequality and personal violence. The explanation for the correlation isn't completely clear; there are a number of possibilities.
You're trying too hard to find a correlation here. You don't know these people, you don't know what they intended. You try to compile statistics and correlate them to a result that amounts to nothing more than speculation.

I definitely see a correlation between how many things a company gets right and how fast a company grows.
