Love is important, but it is not the only factor. I think we both agree that future plans, e.g. whether or not one wants to have children, are important factors that should not be overlooked. I believe that economic status, religious and political beliefs and affiliations, risk tolerance, etc. are also important considerations. None of them is a deal-breaker, but these are all things one should carefully consider before getting married.
With the current divorce rates, the odds are greater than 50% that bank balances will come into play eventually. Love doesn't pay the mortgage at that point.
I'm divorced. The divorce was amicable. Two people sincerely trying to not screw each other over as they leave does make a difference in real terms.
Furthermore, the high general divorce rate does not actually mean that any given individual has a greater than 50% chance of ending up divorced. That is not how that works.
