Final answer:
The difference between white and nonwhite ethnic groups in the United States is long enduring, despite declining individual and institutional racism.
Step-by-step explanation:
The statement is false. While individual and institutional racism may be declining in the United States, the difference between white and nonwhite ethnic groups is indeed long enduring. This is due to the long-term effects of historical racism and systemic discrimination, which have resulted in inequalities in education, wealth, employment, and other areas of society.
For example, students from lower socioeconomic backgrounds may not have the same opportunities as those from wealthier families, leading to disparities in education.
