Modern minimum wage systems have operated for more than a century. Some Pacific countries were among the pioneers in establishing minimum wages. Minimum wage systems are used to achieve many aims, some of which conflict. These aims include promoting social justice, alleviating poverty, promoting economic development, setting benchmarks for other wages and social security payments, and controlling inflation. The Asia Pacific region has only a small number of countries with adequate minimum wage systems. There are many deficiencies in the various systems. They often do not cover all workers, are often set at unrealistically low levels, or are enforced inadequately.
