However the most economic crisis on people in Indonesia is the collapse of Indonesia's currency and the consequent exposure of the private sector to massive unrepayable foreign debt has had a devastating impact on employment, especially in urban areas. Accurate figures on the extent of job losses are impossible to obtain, but most estimates put the figure at around two million. It is often assumed that wage-workers in developing countries can return to their villages if they lose their city jobs and, indeed, this was often the case in the past when the wage sector of the workforce was very small. But the transformation of the Indonesian economy in the last two decades has meant that rural areas can no longer function as a 'shock-absorber' for unemployment. This is particularly true of the most populous island of Java where the majority of the workforce is now employed in secondary industry and services, with a minority still employed in agriculture.
