This issue involves personal values and social attitudes. I don't think that older unmarried people should be generalized as irresponsible. Marriage choice is a highly personal decision and is affected by a variety of factors: 1. Personal pursuits are different-some people may prioritize career, education, or other life goals 2. Changes in the concept of marriage-Modern society has a more diverse view of marriage time 3. Economic and realistic factors-realistic conditions such as housing and economic pressure may lead to postponement of marriage 4. Personal growth rhythm-Everyone's life trajectory is different from the time they are ready to enter marriage The sense of responsibility is reflected in many aspects, such as attitudes towards oneself, family, work and society, rather than just judging by marital status. Equating being unmarried at an older age with being irresponsible reflects an overly simplified view that ignores the complexity and diversity of personal choices.
