Marx himself said it
That entrepreneurs add value. A thriving entrepreneurial ecosystem is indeed what provides real, tangible growth - improving the circumstances of all connected. The social engineer architects of the Swedish model were well aware of that 80-odd years ago too.
"Economic growth" in itself is a skewed term used to punt sophistry by economists - witness many countries with high "economic growth" figures being shitefests to actually exist in, because the real growth is wasted propping up the infrastructure of capital and socialising losses.
Sweden has something very precious - a real social contract that enables it to gain more for less - it's a far more entrepreneur-friendly here than so-called "liberal" economies, while still protecting the situation of the most vulnerable in their society to a high degree. Now I'm talking about entrepreneurs mind you, not people bouncing shedloads of virtual money around.
That this tiny, high-tax economy has pretty much held it's own up against the behemoth predatory economies of other western nations is testament to it's workability. Notice that what brought down en even tinier, but similar and otherwise pretty well-run economy in Iceland was nothing other than international capital.
