Of course everywhere is different, but where I live that generally is a given. Prenups protect only the assets acquired before a marriage, where assets required after the wedding are automatically 'joint' assets. You can write in a clause that, for example, says "All of Mary's financial assets acquired from her career as a day trader shall be hers alone in the event of a divorce" (or somethingDate: 4/29/2009 5:19:09 PM

Oh, I don't know why I'm stirring the pot with this -
-but I don't get the argument 'Why should I get what he had before we met?'
I would use the pre-nup to secure and safeguard future wealth not solely for existing wealth.
I feel they are particularly useful when 2 people enter the marriage but over time one supports the other in furtherance of that other's career. Either by living in another location, child-rearing or other support methods. If not for the fact that the non-benefiting spouse took on that burden the career benefiting spouse would not achieve the level of success they achieve. So when the marriage dissolves and the supporting spouse finds themself in the labour market they often cannot enter at the same level they left and certainly not on a comparable level had they not left. So I feel they deserve to share in the future success of supported spouse. But in the event of marital breakdown neither spouse would choose to be 'fair' to the other. Hence why I feel a pre-nup signed when times are good will often be more favourable than that fought out after he/she finds a pair of undies in the glove compartment.

There are exceptions, but that's my general understanding for my area.
