Basically the number you are looking for is global real GDP growth. This also misses the mark in many ways but it's the closest easy proxy for what you want. So just take global real gdp growth and figure out the ratio that went to the 1% .

Note, life could become worse for almost everyone, while real wealth is created. I would argue that's pretty much what is happening. It doesn't mean real resources weren't created or extracted and someone owns those things.

The idea of altering these figures to account for happiness or quality of life is a fallacy in my opinion. GDP should be measured the way it is. Decmocracies need to figure out their own definitions of "happiness" or whatever you want to call it and optimize for those parameters. But there is no combined measure that covers both.
