There is no doubt that gender distribution is unbalanced in many occupations, so I agree that some jobs are more suitable for men than for women and vice versa.
Men clearly outnumber women in some industries such as manufacturing, mining, logging, etc. A lot of physically demanding tasks need to be done and assuredly, men can perform better than women in doing heavy manual labor. Men also play a dominant role in some sectors that involve a great deal of fighting and violence like the police and army. With men at the forefront facing criminals and enemies, women are expected to stay away from the crime scenes and battlefields, where intense fighting and cruel killing are common.
There are also some female-dominated professional fields in which women represent the majority and make greater contributions than men. The feminine traits such as gentleness, patience and meticulousness give women an advantage in nursing, teaching, clerking, etc. When taking care of the elderly, educating children and dealing with numbers, females usually outperform their male counterparts.
Despite what has been discussed above, I do not think it is right to exclude males or females from certain professions just because of their gender. As the automation of machines and weapons has reached a high level, women can do a good job in the factory or in the army. Similarly, men are encouraged to be kindergarten teachers so that they can help boys develop masculinity from a young age.
To conclude, there should be no gender discrimination in the workplace, or stereotype in judging a person’s choice of career, but an undeniable fact is that, generally, men and women have different qualities, which make them fit certain jobs.
