This won't do. If we were to go 400 years into the past to Western Europe, you would see that about 15 percent of the population knew how to read. And I suspect that if you asked someone who did know how to read, say a member of the clergy, 'What percentage of the population do you think is even capable of reading?' They might say, 'Well, with a great education system, maybe 20 or 30 percent.' But if you fast forward to today, we know that that prediction would have been wildly pessimistic, that pretty close to 100 percent of the population is capable of reading.
