Ch-changes
Paul Krugman replies to commenters who think he underestimates the impact of technological advances such as mobile phones and the Internet:
If I had to make a guess, [I’d say] the fastest progress in the technology of daily life—the biggest changes—probably came between the 1880s and the 1920s.
Sounds right—widespread rail networks, indoor plumbing, telephones, motorcars, nitrogen-fixing fertilizer, electricity, not to mention non-technological changes; women’s suffrage, workplace protections, (and, if you lived in Bismarck’s Germany, universal health care).
What era (say, 25-40 year period) would you choose?
