[单项选择]If income is transferred from rich persons to poor persons the proportion in which different sorts of goods and services are provided will be changed. Expensive luxuries will give place to more necessary articles, rare wines to meat and bread, new machines and factories to clothes and improved small dwellings; and there will be other changes of a like sort. In view of this fact, it is inexact to speak of a change in the distribution of the dividend in favor of, or adverse to, the poor. There is not a single definitely constituted heap of things coming into being each year and distributed now in one way, now in another. In fact, there is no such thing as the dividend from the point of view of both of two years, and therefore, there can be no such thing as a change in its distribution.

[填空题]If life expectancy were a marathon, the United States is fading from the pack. Although everyone is living longer, the inhabitants of other industrialized nations have made more dramatic strides in life expectancy than Americans have, which consequently leads to the result that Americans, who are once on par with Italy and New Zealand in the middle of the pack now rank below Spain and Greece near the end.
On the face of it, this shouldn’t be happening.
Healthier nations are usually wealthier nations. The United States ranks only after Luxembourg and Norway of the 30 richest nations belonging to the Organization for Economic Cooperation and Development (OECD), but it now ranks 22nd in life expectancy.
The problem could be anything but inadequate healthcare spending. The US spends $1 of every $7 of its gross domestic product on healthcare, more than any other OECD nation that typically devotes less than $1 in $10 of GDP to the sector. Per person, that works out to an
