Why is marriage and education considered so important?

Why is it that every kid once they grow up get this pressure of getting married and having some sort of education because somehow education is tied with reputation and social status. If your broke then nobody will respect you. But if you have money then some people will end up calling you arrogant and show off. And marriage is like constantly being reminded oh your this old look at your cousins and friends settling down. Not only do they want you to get married but they also expect to have an ideal partner is that compitable with joint family. And I hate how this old stigma where most people favor a boy over girl. And saying horrible things like we need a son not girl. Is like at the end, they are all children. Why is there so much difference of value.
