Like I said before, yes, if the 2 parties are significantly different in wealth status. Otherwise if one party insists on prenup, the marriage is starting out unnecessarily with consternation.
There wasn't a significant difference at the start of our marriage. I had a net worth of -$5k and she was -$20k. Over the 13 years of marriage, I created a net worth of close to a million, she had negative several hundred thousand (that I covered). My income has gone up 12x since we got married and she, despite having a college degree when we got married and I did not, actually makes less money now than then. Assuming someone will stay the same in today's world for 60 years is crazy. A pre-nuptial agreement doesn't have to be crazy - it can simply state what you save is yours and what I save is mine, lay out rules for potential alimony or not, etc.
For a man under the age of 45 with an IQ 1 Std Deviation above the mean I think a pre-nuptual agreement is the ONLY way to go. Remember, you aren't just married to her, but the state with marriage today. That pre-nupt protects from both.
