„For two hundred and fifty years, from the second half of the eighteenth Century on, Capitalism was the dominant social reality. For the last Hundred years, Marxism was the dominant social ideology. Both are rapidly being superseded by a new and very different society. The new society – and it is already here – is a post-capitalist society… The center of gravity in the post-capitalist society – its structure, its social and economic dynamics, its social classes, and its social problems – is very different from the one that dominated the last two hundred and fifty years“
