Furthermore, the plague's great population reduction brought cheaper land prices, more food for the average peasant, and a relatively large increase in per capita income among the peasantry, if not immediately, in the coming century. Since the plague left vast areas of farmland untended, they were made available for pasture and put more meat on the market; the consumption of meat and dairy products went up, as did the export of beef and butter from the Low Countries, Scandinavia, and northern Germany. However, the upper class often attempted to stop these changes, initially in Western Europe, and more forcefully and successfully in Eastern Europe, by instituting sumptuary laws. These regulated what people (particularly of the peasant class) could wear, so that nobles could ensure that peasants did not begin to dress and act as a higher class member with their increased wealth. Another tactic was to fix prices and wages, so that peasants could not demand more with increasing value. In England, the Statute of Labourers 1351 was enforced, meaning, no peasant could ask for more wages than in 1346. This was met with varying success depending on the amount of rebellion it inspired; such a law was one of the causes of the 1381 Peasants' Revolt in England.
