Actually Denmark, Norway or Finland accomplish high education level throughout society. And there are good studies showing that a overall better educated society with eaqual opportunities deliver a resilient strong economy. I would count those countries good example on how countries that deliver good opportunities to all people living in the country can deliver persistant growth. Meanwhile there is a good record on that an economy where rich people accumulate all the wealth while the middleclass is empoverished, the over all economic power shrinks. And this is happening in countries, which almost do not tax very rich people and companies.
