Causes
Each labour rebellion had its own particular circumstances, but a common pattern can be discerned: the underlying causes were economic. With the exception of the mineral-extractive industries - oil in Trinidad and bauxite in British Guiana - the British West Indian economies were largely dependent on a narrow range of agricultural exports. Thus, they were highly vulnerable to reduced demand or a serious downturn in Britain and Europe. The sugar industry, which remained the mainstay of the colonial economies, had long been in a critical state but had revived during World War I as warfare disrupted European sugar beet production. In the postwar years, sugar prices fell sharply as world supply exceeded effective demand. The British government's policy of subsidizing domestic sugar beet production further depressed prices. The prices of other agricultural staples, including cocoa, coconuts, limes and bananas, also slumped to unprofitable levels due to worldwide overproduction. In some cases agricultural commodities suffered from the effects of plant diseases and hurricane damage. The crisis in the colonial economy was exacerbated by the global economic Depression which further reduced demand for British Caribbean exports in the 1930s.
The pervasive economic Depression in the colonies had far-reaching consequences for the working classes. Employers in some industries drastically reduced wages. Social conditions deteriorated as unemployment and underemployment increased (which an inadequate social welfare system could not address), factors which were worsened by sharply increased population growth, itself the result of a significant downward trend in the region's mortality rate as health conditions improved. The cost of living also went up: it was a sudden upsurge in 1937-38 that led to strikes in Jamaica. Emigration outlets were closed, which created a frustrating sense of being shut in and of being denied opportunity and choice.
Other general causes were the longstanding grievances of the West Indian peasants against the plantation owners. Historically, the peasants occupied the least fertile lands and were bullied by the owners. They had problems with land title, poor technology, lack of finance and marketing assistance, and poor means of transporting produce from the farm to the market. These and other grievances stimulated peasant participation in the disturbances. Furthermore, there was a rapid growth of working-class consciousness. Labour unions had been well-organised in Guiana and Jamaica since the 1920s. The British Guiana Labour Union dated to 1919, and the Longshoremen Union had a chapter in Jamaica from the early years of the century.
In addition, there was a general increase in nationalist and pro-independence sentiments in the 1930s. The labour unions were organised as general political organisations or broad-based social movements. They campaigned for better wages and working conditions, the transformation of the colonial system and political independence for the colonies. Moreover, West Indians had rising expectations, as many had travelled abroad and experienced living conditions in Britain and the US. They wanted the same high standard of living at home, wished to be accorded respect as trained professionals and desired opportunities for upward mobility. Instead, they remained trapped in the system's political, economic, social, colour and racial hierarchies. Ideologies such as Marxism and Fabian socialism gained currency.
