396 portion, not of his whole means, but of his superfluities. An income not exceeding 50l. should not be taxed at all, either directly or by taxes on necessaries; for as by supposition this is the smallest income which labour ought to be able to command, the government ought not to be a party to making it smaller. This arrangement however would constitute a reason, in addition to others which might be stated, for maintaining taxes on articles of luxury consumed by the poor. The immunity extended to the income required for necessaries, should depend on its being actually expended for that purpose; and the poor who, not having more than enough for necessaries, divert any part of it to indulgences, should like other people contribute their quota out of those indulgences to the expenses of the state.

The exemption in favour of the smaller incomes should not, I think, be stretched further than to the amount of income needful for life, health, and immunity from bodily pain. If 50l. a year is sufficient (which may be doubted) for these purposes, an income of 100l. a year would, as it seems to me, obtain all the relief it is entitled to, compared with one of 1000l., by being taxed only on 50l. of its amount. It may be said, indeed, that to take 100l. from 1000l. (even giving back five pounds) is a heavier impost than 1000l. taken from 10,000l. (giving back the same five pounds). But this doctrine seems to me too disputable altogether, and even if true at all, not true to a sufficient extent, to be made the foundation of any rule of taxation. Whether the person with 10,000l. a year cares less for 1000l. than the person with only 1000l. a year cares for 100l., and if so, how much less, does not appear to me capable of being decided with the degree of certainty on which a legislator or a financier ought to act.
