Why people want a wife or husband from family of a higher class

Many people do not agree with the point to get the other half from a higher class, though someone sticks to this!
Those who want to get the other half from a higher class can be divided into two kinds:
1 Marry someone from a higher class or whose family is rich, take advantage of the money or social position to live a comfortable life! Most girls finding a husband who is rich own such ideas.
2 Marry someone richer, and find the reason or cause for them to become rich, improve yourselves, I think this way may be a wiser way. If you do this, you do not rely on the rich of family of your wife or husband, you do not eat "soft food"; and you rely on yourself, so they respect you, and dare not look down upon you!
Through the analysis, we can see that, if you want to improve yourself more quickly, finding the other half from a higher social class is of no acuse, and I think you can control yourself, catch each chance to improve yourself, and realize your life dream!
So, go and find the other half from a richer family or a higher class!
