I think a good prerequisite for both parties to the marriage is that both are financially independent prior to signing on the dotted line. They wouldn't admit it of course but the free meal ticket element of deciding to marry is a real factor involved for many, not exclusively on the woman's side of things but more so than the other way around based on what I've seen in my social circle.
When money comes in the front door love can often run out the back door to the divorce courts for a nice financial package nest egg.
For men especially it's a case of Caveat Emptor in order to avoid buyers remorse and not being able to hand the receipt back in for a refund!
The last few women who have asked me out have been gold diggers, one asked me straight out did people in my profession make much money lol some of them cant hide it but its the ones who can that would worry you.
I always let on that I havent a penny, 99% of the time you never hear from them again.
