Accumulation isn't the same thing as concentration. Everything I've seen on post-Civil War US trusts suggests they were far bigger as a percent of GDP and in terms of market share than their Information Age counterparts. And what's even more striking is the horizontal division of labor: firms from China, India, Eastern Europe, and Latin America are major players in the world-market. Boeing and Airbus may be the Big Two in aerospace, but they're at the apex of vast networks of decentralized suppliers.
