The evolution of average earnings gives an indication of the wellbeing of employees. This chapter examines the purchasing power of weekly earnings by comparing the price of a loaf of bread, a pound of butter and a pound of sirloin beef in selected years to nominal average weekly earnings of industrial workers in the industry sector in the same year.
A loaf of bread cost 5.5d (5 and 1/2 pence) in 1938 when the average industrial wage was £2 6s 4d (2 pounds, 6 shillings and 4 pence). Thus, a loaf of bread accounted for 1% of the average weekly industrial wage. In 1968, average weekly industrial earnings were £14 2s 5d and a loaf cost 1s 10.5d, 0.7% of the weekly wage. By 2000 average weekly industrial earnings were £364.80 and a loaf of bread cost 78 pence, accounting for 0.2% of the weekly wage. These figures, illustrated in Figure 6.1 below, show how the price of selected household items as a percentage of average weekly earnings have fallen significantly over the period.
In 1938 a pound of butter cost 1s 5.2d and a pound of sirloin beef cost 1s 0.7d, these prices equate to 3.1% and 2.3% of the average weekly industrial wage. By 1955 butter and sirloin were the same price, accounting for 3% of the average weekly wage. Since then the price of both products, as a proportion of the average industrial wage, has decreased significantly. In 2015 a pound of sirloin accounted for 1.1% of the average weekly wage. The relative price of butter fell at a greater rate and now accounts for 0.4% of the average industrial wage.

| 1985 | 0.3 | 0.6 | 1.8 |
| 2000 | 0.2 | 0.5 | 1.2 |
| 2015 | 0.2 | 0.4 | 1.1 |
