Legal solutions for horizontal gender segregation include implementing anti-discrimination laws that prohibit employers from segregating jobs based on gender. This can be achieved through the enforcement of equal pay laws, which require employers to pay men and women equally for the same work. Additionally, promoting gender diversity and inclusion through affirmative action policies can help address horizontal gender segregation by encouraging the hiring and promotion of women in male-dominated industries. Lastly, providing legal avenues for individuals to report and seek redress for gender-based discrimination in the workplace is crucial in addressing horizontal gender segregation. **

Segregation was deemed unconstitutional in the USA because it violated the principle of equal protection under the law guaranteed by the 14th Amendment of the Constitution. The Supreme Court's landmark decision in Brown v. Board of Education in 1954 declared that separate facilities for different races were inherently unequal and therefore unconstitutional. This ruling paved the way for the dismantling of segregation laws and practices across the country, leading to greater civil rights and equality for all Americans. **
