Arnold Kling asks,
I've been away, mostly in Prague (where the big economic question is why so many older buildings have so many fancy details. My answer is that there must have been a very unequal distribution of wealth, so that rich folks could afford to hire a lot of labor for building)[?]
I don't know specifically about Prague, but I do get this question a lot in the form of allegations that product quality has deteriorated through time. People making this allegation usually blame free market capitalism. It comes in the form of, "Houses built 100 years ago were better built and of higher quality relative to homes built today." As if laissez-faire capitalism was less prevalent 100 years ago than it is today.
