Mass production of cars, standardization of education, and government programs increased women's involvement outside the home.
Mass production of the car and expansion of roadways resulted in women being more involved in society outside the home. The ability to travel more easily and independently due to cars and improved roads opened up opportunities for women to participate in activities beyond the confines of their homes.
Furthermore, standardization of education and reorganization of schools played a crucial role. As more women attained formal education, entered the workforce, and engaged in public life, they began to question traditional gender roles and pursue opportunities outside the home.
Finally, through government sponsored programs that aimed to promote gender equality and empower women, more females were encouraged to actively participate in communities and push for social and political causes, leading to increased involvement outside the home.
