Why do people choose to have children if it is so much hard work

People choose to have children for a mix of emotional, social, biological, and practical reasons: - Emotional fulfillment: many expect love, joy, purpose, meaning, and deep attachment from parenting. - Biological drives: evolved instincts and hormonal influences (e.g., oxytocin) motivate care and reproduction. - Cultural and social norms: family expectations, religious beliefs, and social approval make parenthood a default life script in many societies. - Legacy and continuity: children provide a sense of continuity, passing on genes, culture, name, or values. - Practical and economic reasons: in some contexts children provide labor, old-age support, or social security. - Identity and life projects: parenting is a major way people create, test, and express personal values and achievement. - Uncertainty, planning limits, and optimism bias: people underestimate future burdens and overestimate their ability to cope.
