Children, education, medical expenses, recreation, old age & marriage, etc. should constitute _______ of the total minimum wage

The text you provided seems to be a statement or a question that is missing some information, specifically a percentage or proportion that should represent the total minimum wage. However, this percentage can vary greatly depending on the specific laws and regulations of different countries, states, or regions.

In general, the total minimum wage should be enough to cover all basic needs of a worker and their family, including food, housing, education, health care, and other necessary expenses. Some guidelines suggest that these costs should not exceed 60-70% of the total minimum wage, leaving some room for savings and unexpected expenses. However, this is just a general guideline and the specific percentage can vary.

It's also important to note that the minimum wage is often a subject of debate and can be influenced by many factors, including the cost of living, the state of the economy, and the political climate. Therefore, it's always a good idea to check the specific laws and regulations in your own area.
