Good point. Interestingly education is one of the industries that seems to be least disrupted by technology.
The authors point somewhat still stands for healthcare, though. He uses 1939 as a benchmark. Penicillin was first manufactured in 1942. Today a generic antibiotic is just a few cents a pill. Some of the most essential healthcare that would have been just a dream in '39 is nearly free today.
Healthcare costs may be drastically increased in the US (although just $60/mo here in Canada) compared to what they used to be but the offering has changed completely as well.
