If we try to steer the ship back to the topic at hand...here's why we should be concerned that Europe's private sector isn't growing much or innovating much.
It turns out, Europeans entire way of life is funded by taxing the activity of the private sector and redistributing that money to things like healthcare, education, pensions, etc. Innovation (increased productivity) is the only way to reliably grow this pie, and innovation is exclusively the domain of the private sector due to the competitive pressures of markets.
If our private sector is entirely composed of aging industrial-age conglomerates waiting to be disrupted by more dynamic and innovative Chinese competitors (China is rapidly becoming better at the things European industrial companies used to dominate), our entire society is at risk. Militarily, we're sitting ducks, and economically, we are as well.
Modern Europe is economically heading the way of the Soviet Union, with an increasing share of GDP driven via centrally controlled government spending (we're now at over 50% on average in the EU, the Soviets were around 70-85% at peak).
Meanwhile, The Chinese Communist Party has ironically created one of the most dynamic, capitalist systems on the planet. The Chinese supposedly "communist" economy is in fact more market-driven than even the US economy (33% government-driven vs 36% government-driven), and you can see this in the numbers: https://www.imf.org/external/datamapper/exp@FPP/USA/FRA/JPN/...
It doesn't take a Phd to understand that a much larger and more unified population in China, with a more unleashed private sector, is going to eat the lunch of the smaller, disjointed micro-economies in Europe. And this doesn't even factor in the rise of industrial investment in the US in recent years.
