I was born in an upper class, old money family. Is it shallow of me to not want to marry a middle classed man and downgrade my lifestyle?

We often hear of female hypergamy. I don't want to marry a man richer than me, only a man "on my level" who I won't have to downgrade my lifestyle for. Does this make me shallow?
