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 be allocated to "Children, education, medical expenses, recreation, old age & marriage, etc." from the total minimum wage.

However, this proportion can vary greatly depending on the specific laws and regulations of a country, the cost of living, and other socio-economic factors. It's also important to note that minimum wage is typically meant to cover basic living expenses for an individual and doesn't necessarily account for all these factors.

In many guidelines, it is suggested that no more than 50% of income should go towards needs, which would include items like housing, food, healthcare, and minimum loan payments. 30% should go towards wants, which could include recreation and other non-essential expenses. The remaining 20% should go towards savings or paying off debt.

But again, these are just guidelines and can vary greatly depending on a variety of factors. For a more accurate and personalized answer, it would be best to consult with a financial advisor or someone familiar with the cost of living and wage laws in the specific area in question.
