Can advertising foist an inferior product on the consumer? Bitter experience has taught me that it cannot. On those rare occasions when I have advertised products which consumer tests have found inferior to other products in the same field, the results have been disastrous.

It strikes me as bad manners for a magazine to accept one of my advertisements and then attack it editorially - like inviting a man to dinner then spitting in his eye.

Does advertising corrupt editors? Yes it does, but fewer editors than you may suppose... the vast majority of editors are incorruptible.
