Looks at the transition from "personal" to "organized" ( or for us commies "imperialist monopoly") capitalism through the prism of the 200 largest enterprises in the UK,US and Germany between 1880 and 1930.
A little boring but quite informative.
Also shows how the British refusal to move from personal "gentlemen's" capitalism to bureaucratic monopoly structures helped speed up the time when the sun set on the Union Jack.

Just wonderfull reading - the structure of the book is a slurpee for the understanding of the succes and terror of Western civilization as we know it.

actually i didn't read the whole thing...it's a heavy tome. but skimmed it, and took some valuable lessons away with me.
