If you read the book carefully, it was not suggested that public-key systems where safer than a OTP system. The problem with OTP is distribution of the pad's. That problem is solved using a public-private key scheme.
Another problem with OTP's is creating a pad that is random enough. As you might know, using a randomizer function in a computer is almost never really random. Although it is possible to create fuly randomized values for a OTP (considering creating the key and distributing it), using OTP it is definitely more expensive than using public key's.
So for the latter, cracking a code from an OTP system depends on analysing one stolen OTP and trying to find the randomizer function that was used to create it.
