Tony Judt in Post War (https://www.goodreads.com/book/show/29658.Postwar) actually claims that this is patently false. That Germany actually came out of WW2 with most of its industry intact (it was away from the most bombed cities and majority of fighting actually happened in France/Poland/USSR) and was in significantly better shape than Frace and UK industry-wise. As an added bonus, the industrial lines were freshly retooled, significantly more modern than the ones in France and UK and its wartime focus could be rather rapidly converted into highly profitable peacetime industries that were highly sought after in 20th century economic boom (chemistry, car manufacturing, electronics, etc.)
The fact that BRD didn't have to support and invest into standing army also funneled investment into emerging industries - investment that was way slower to come in destroyed France and exausted UK.
Was he wrong? Are there any sources contradicting his research?
