Letter: It doesn't add up

From Professor Klim McPherson

Sir: If Helen Wilkinson ("One woman's equality is another's poverty", 10 March) is to base her argument on "simple arithmetic", it would be good if she were able to demonstrate greater proficiency. Household inequality certainly does not double when lawyers marry lawyers and factory hands marry factory hands. And two people earning twice the average do not earn four times as much as two people on the average salary.

Yours faithfully,
