Leaving the context of the topic as originally presented, being a good salesman &c. to one side, & thinking about it more from the standpoint of examining into some of the causes of the astonishing societal decline that has occurred over the past sixty or seventy years one can't help but notice that the intelligence of the general public has suffered a catastrophic decline. Modern people are sinking ever lower, I'm afraid that if God permitted things to go on as they're going now for another 100 years, the greater part of mankind would be reduced mentally almost to the level of the very beasts, they would become creatures like the eloi depicted in H.G. Wells's The Time Machine. Books printed for the general public 150 or 100 years ago are often unintelligible for moderns. They were never taught basic things such as the meaning of common grammatical terms. An Englishman of say 1880, who wanted to learn German would get a German grammar & learn how to compose grammatically correct sentences by memorizing things such as that any noun following the preposition wegen, because of, on account of, must be in the genitive case, wegen des regens, on account of the rain &c. Most young people now would find such a book useless, case? genitive? preposition? what are those things? They weren't taught history, geography, foreign languages, mathematics & so on, they were taught what a great man the communist negro agitator King was & how they should be ashamed of their own culture & ancestors. For the most part their minds have been entirely enervated by the wonderfully successful state schools, which are set up for this purpose. If God does not intervene the situation is utterly hopeless.
