The future of human marriage

• What is the future of human marriage?

• In human social affairs, discrimination is treatment or consideration of, or making a distinction in favor of or against, a person based on the group, class, or category to which the person is perceived to belong. These include age, color, convictions for which a pardon has been granted or a record suspended, disability, ethnicity, family status, gender identity, genetic characteristics, marital status, nationality, race, religion, sex, and sexual orientation.
Combining the above materials, write an essay on:
What are the root causes of discriminatory attitudes in life?

• Some people say, price, snob value, and value as relic have little to do with artistic merit. The first is to do with rarity, the fluctuations of collectors’ tastes, and the manipulations of the art dealers; the second is a matter of social rivalry; the third is psychological, to do with the way we treat objects.
Do you agree with that? Why or why not?
