What's wrong with the world

I just finished 'What's wrong with the world', and I find it a difficult book to summarize. Luckily, Chesterton gives a nice example in this conclusion, in which he emphasizes his main point.

A little while ago certain doctors and other persons permitted by modern law to dictate to their shabbier fellow-citizens, sent out an order that all little girls should have their hair cut short. I mean, of course, all little girls whose parents were poor. Many very unhealthy habits are common among rich little girls, but it will be long before doctors interfere forcibly with them. Now, the case for this particular interference was this, that the poor are pressed down from above into such stinking and suffocating underworlds of squalor, that poor people must not be allowed to have hair, because in their case it must mean lice in the hair. Therefore, the doctors propose to abolish the hair. It never seems to have occurred to them to abolish the lice. [-]

Now the  whole parable and purpose of these last pages, and indeed of all these pages is this: to assert that we must instantly begin all over again, and begin at the other end. I begin with a little girl's hair. That I know is a good thing at any rate. Whatever else is evil, the pride of a good mother in the beauty of her daughter is good. It is one of those adamantine tendernesses which are the touchstones of every age and race. If other things are against it, other things must go down. If landlords and laws and sciences are against it, landlords and laws and sciences must go down. With the red hair of one she-urchin in the gutter I will set fire to all modern civilization. Because a girl should have long hair, she should have clean hair; because she should have clean hair, she should not have an unclean home; because she should not have an unclean home, she should have a free and leisured mother; because she should have a free mother, she should not have an usurious landlord; because there should not be an usurious landlord, there should be a redistribution of property; because there should be a redistribution of property, there shall be a revolution.
