> If you're right about the cost of electricity "staying the same" — by which I assume you mean that, in the US, it increases in line with the BLS CPI?

Yes I meant real price, not nominal.

US electricity is somewhere around a third from coal.

I would be interested in a study showing a 15-30x increase in similar-quality construction materials.

The fixation on gold makes no sense to me. It's just a commodity, not a super useful one either. Gold's price floats wildly based on people's fears. It's not like everything became 4x more expensive between 2000 and 2015.

We were debating precisely which data series is best for computing the "real price" from the nominal prices. But it seems you take me for a fool and beg the question.
