It is true that poor wealth students have to do many extracurricular activities after class. They might not have full concentration put in study in order to help their family. The educational failure of poor students is bias and I have seen many kinds of this example when I was in school. For example, the clubs like finance clubs and investment clubs are reserved for those wealthy students, who have money to do the purchase and experience the real capital market.

Poor students cannot succeed in school and cannot lift themselves out of poverty is the problem of our educational structure. Poor families usually don't pay as much attention to education, while rich families tend to spend more energy on raising their children, which leads to a negative cycle where children from rich families become better and more capable of earning money, while the wealth gap between children from poor families and children from rich families gets bigger and bigger.

SAT have been accused to have economic bias as the exam fee is pretty expensive and only hold in specific country. For example, there are no SAT test centers on the China mainland. That also causes the potential regional/ race bias for Chinese tester. Even we would like to close the race gap/ wealth gap, the process need to went through a long time to achieve our goals.

In China, we have "High School Entrance Examination", just like SAT/ACT, everyone in this country went through this exam, and based on your grade enter into universities. This way is pretty fair for those students without economic privilege and would like to change their fate through study.

Having a diversity background students for one class allows for teacher to be inclusive and consider from different aspects. It also help us to realize the racial/gender bias happened in classroom/ social. Multiculturalism could help us understand the different culture and also have the realization of protect and respect the different views.

Here is an example of how race and gender might influence the education experience. Someone might worry about their color and afraid to speak in the class. The minority group might gain less class participation than others.

This is the goal for American people, not only because of their diversifies race groups, but also on their huge size of the community. However, democratic control not as perfect a strategy as they thought, localism could deal with local idiosyncrasy, if they would like to achieve democratic and equality, they have to lose something.

I think this is a true fact. From the viewpoint of outsider, wealthy families could provide strong background for their child and give them a quite easier track towards success. The child could gain better educational resources and more chances during work searching. We have to admit this is a true and there exists some priority and inequality in our society. We cannot achieve perfectly balance on this thing.

The ideology for US and China is quite different. Because most Chinese families only have one child each family, any major decision made by a child means affecting the fate of the entire family. Chinese children may not have the freedom to choose what they want, and they carry the responsibility of the entire family, which means that failure is more difficult for them to accept.
