It could be that married couples get large financial gifts/boosts from their parents more often than unmarried couples. If this is the case, then the involvement of the parents in the marriage ceremony may be a major factor in this outcome.

I wish! Though, there might actually be a correlation here, since parental stability, income levels and education affect marriage/divorce rates, and parents with their act together would have more money to give, and more of a chance of a meaningful estate to bequeath.
