How wealthy are modern day humans compared to preindustrial times? I would like to see a quantitative wealth comparison between the average human in a hunter gather or agrarian society to average human in the today's world.

I'm mostly interested in how the discovery of natural energy resources combined with Newtonian physics influence on technology has changed the world in terms of relative worth of a human.

The kind of answer I'm looking for would be something like: We are 10, 100 or 1000 times more wealthy based upon x. X being what ever you use as a basis to create that comparison.
There is significant debate about whether such x exists.

For example Louis XIV had things in his estate that are not in mine (I do not have two palaces). But there are also things in my estate that were not in his. I have access to 21st century healthcare, dental care, the internet, I can flush after going to the toilet...whose lifestyle is 'worth' more?

The comparison gets more difficult the farther you go back. So hunter gatherers, with tribal ownership, without any currency and frequently without any sort of industry are probably uncomparable to modern humans via any 'wealth' based standard.
