The Government should increase subsidies on welfare services and public housing in order to narrow the poverty gap, academics say. City University lecturer Wong Hung said official figures showed more than 600,000 people living in poverty without enough food. Mr Wong said wage increases from the manufacturing sectors were low while rents were rising. Imported labourers from the mainland would further dampen wages and increase the gap between rich and poor, he said. His remarks to the City Forum came in the wake of a report from the Hong Kong Social Security Society that the top 10 per cent of households shared 42 per cent of the territory's gross income, while the bottom 50 per cent shared just 19 per cent of the wealth. Fok Tin-man, spokesman for the Society of Community Organisation, said the Government should review industrial policy and provided retraining courses for unskilled labour in order to avoid more falling into poverty traps. But Andrew Leung Kin-pong, Director of Social Welfare, said the poverty gap was not serious when compared with other advanced economies. But he said the Government would try to review social assistance, especially to the elderly.
