Source of GDP data: https://www.zerohedge.com/economics/europe-was-once-bigger-us-economy-what-happened
Gold and oil prices from goldprice.org. I read the open and close numbers off a yearly chart and then took the average as the yearly price of the commodity. Note I took the GDP numbers straight from the article and did nothing to validate them.
The article shows a chart (similar to pic1) of EU and US GDP. It occurred to me that it wasn't a fully fair comparison since the US has the advantage of the US dollar being the world reserve currency, so I wanted to see what things looked like in real terms. Being a PM bug I first used Gold (Pic 2), an oz of AU is an oz of AU. This shows a interesting result as both are shown as actually declining. Gold does have the issue however of being a suppressed/manipulated market so I then did versus oil (pic 3). Oil is less of a controlled market and has the advantage of being the primary energy source.
FInally, yes I know GDP is heavily massaged, etc. etc.
Note than in all three charts the basic premise of the article holds up as the US is doing better than the EU but the details are telling.
If anyone is interested I will post the spreadsheet with all the data so you can play with the numbers yourself.
