These do not scale to 30% of GDP in the same way high value B2B industrial equipment does (in manufacturing you happily pay $100,000 for a piece of machinery because it can turn inputs into more valuable outputs at scale).
Instead of coming up with incorrect ideas about what the government should “encourage” from the top down, what if European elites focused on cooperating more with their neighbors to open more opportunities and meanwhile let the peasants (the market) figure out the most productive and profitable uses of their time.
If Europeans can’t figure out new valuable areas where they can contribute to the world, than their system isn’t as clever or morally righteous or fantastic as they think it is. I believe if allowed the opportunity, the people would find this positive-sum value to be created. Who do you think founded all the Mittelstand in the first place?
