On the other hand, Europe has lower inequality amongst citizens, and an argument could be made to say that this increases happiness. What they are missing out on wrt fortune 500's is creativity that creates new technologies that pushes boundaries and revolutionizes the world (perhaps an oversimplification of the argument). Though they may not be at the forefront of this, it would be inaccurate to say that they do not benefit from innovations occurring in the world.
My argument is that they currently occupy the coveted position to benefit both from the inequality of other countries yet retain the benefits of a more equal society. Viewing the entire world as an unequal society, the winners would be the ones at the top of unequal countries, followed by the equal countries, with those at the bottom of unequal societies trailing. Ideally the entire world would all have equal societies, but in no situation would I think countries with equality strive for the benefits of those with unequality
