I think to some extent and many people do this - though they wouldn't admit.
I don't see the issue, I actually think smart move - would I rather marry a millionaire that I was averagely attracted to or a bin man I fancied the pants off - sorry but millionaire all day long. However - I am more about personality so I wouldn't compromise on that money or not.
Life is hard, and having someone able to provide a good standard of living is something to value.
HOWEVER would I ever rely on a man with money? Never in a million years. There's a difference between marrying for money and being reliant on marrying for money. If you're the latter then that's an issue IMO.
