Look at the graphic on page 14 and keep in mind our working age population is shrinking and the statistic is in real, not nominal, terms.

Capital investments equalled 17-21% BIP (BIP ~ GDP) over the last decade,
About 2-7% BIP net capital investments in that decade.

Meanwhile, Germany still had a net capital export / trade balance surplus on the order of several per cent GDP.

Better don't look at the UK or US for comparison, for you'd get a shock.
