which of the following causes for inequality passes the supreme court's scrutiny under the equal protection clause of the fourteenth amendment MOST easily?

To adequately answer your question, I would need more specific information about the mentioned causes for inequality. The level of scrutiny applied by the Supreme Court under the Equal Protection Clause varies depending on the classification involved. The Court has historically used three levels of scrutiny: rational basis, intermediate scrutiny, and strict scrutiny.

- Rational Basis: This is the lowest level of scrutiny where the Court presumes the constitutionality of a statute or government action. To pass rational basis scrutiny, the law or action must have a legitimate governmental interest and be rationally related to achieving that interest.

- Intermediate Scrutiny: This level of scrutiny is applied when the classification involves gender or legitimacy. The government must demonstrate that the classification substantially advances an important governmental interest.

- Strict Scrutiny: The highest level of scrutiny is applied when the classification involves race, national origin, religion, or impinges upon fundamental rights. The government must show a compelling state interest and that the classification is narrowly tailored to achieve that interest.

Without specific information about the causes for inequality you mentioned, it is difficult to determine which would most easily pass scrutiny under the Equal Protection Clause. Can you please provide more details or specify the causes you are referring to?
