Adam Smith on bad people

This is another good example of why I love Adam Smith. The Wealth of Nations is really quite a funny book; weirdly, his passages on the driest of subjects are often the most hilarious. Here he compares taxes on luxury goods, like tea, chocolate and port, to taxes on necessities. He says raising the price of luxury goods could actually have a positive effect on society:

"The high price of such commodities does not necessarily diminish the ability of the inferior ranks of people to bring up families. Upon the sober and industrious poor, taxes upon such commodities act as sumptuary laws, and dispose them either to moderate, or to refrain altogether from the use of superfluities which they can no longer easily afford. Their ability to bring up families, in consequence of this forced frugality, instead of being diminished, is frequently, perhaps, increased by the tax. It is the sober and industrious poor who generally bring up the most numerous families, and who principally supply the demand for useful labour. All the poor, indeed, are not sober and industrious, and the dissolute and disorderly might continue to indulge themselves in the use of such commodities after this rise of price in the same manner as before without regarding the distress which this indulgence might bring upon their families. Such disorderly persons, however, seldom rear up numerous families, their children generally perishing from neglect, mismanagement, and the scantiness or unwholesomeness of their food. If by the strength of their constitution they survive the hardships to which the bad conduct of their parents exposes them, yet the example of that bad conduct commonly corrupts their morals, so that, instead of being useful to society by their industry, they become public nuisances by their vices and disorders. Though the advanced price of the luxuries of the poor, therefore, might increase somewhat the distress of such disorderly families, and thereby diminish somewhat their ability to bring up children, it would not probably diminish much the useful population of the country."
