Not all of them can be scientists and engineers, etc., but some of them have talents for such things! Give them a chance! A good many of them have unmistakably artistic gifts! Why not give them a chance too! And the mechanically inclined should have a chance! Why can we not differentiate according to their tastes and gifts?
For even then we shall have enough left to be our hewers of wood and carriers of water; an abundance will remain to do all the work that requires neither brains nor gifts.
But let us stop at once and for ever trying to cram thick heads and poor brains with stuff that cannot possibly be appreciated or understood.

Let us teach their mechanical fingers to do something useful, and give them, even the degenerates, some chance! And we must stop our blind alley occupation for growing lads, for at the end of the alley stands an open door to the netherworld, and through it youthful life passes with little prospect of return..
