I think it would depend on a number of factors that may be personally unique in every case. I couldn't say yes or no across the board.
I do believe whatever assets are acquired or accumulated by the couple starting from the date of marriage are fair game - 50/50 - and many states already have laws which attempt to treat pre-marrital assets in a 'leave with what you brought to the marriage' manner, with certain exceptions.
I also think that the cause of the divorce can be a factor. If one party just decides they want a divorce so they can be free to 'find themselves' and cannot cite any compelling impropriety or wrong-doing on the part of the other as the reason for the divorce, they should not be entitled to the same standing as someone who cites reasons such as spousal cruelty, neglect, infidelity, etc.
But most of this could be avoided if people were a bit more careful to understand their prospective spouses so there are few surprises after marriage. Many couples never discuss things before marriage such as money issues (including debt), child bearing issues (who is going to stay home, if anyone, and for how long), child rearing issues (methods of discipline, each agreeing to enforce the rules and restrictions set by the other), settling disagreements (including when to agree to disagree), among many other issues, so that each knows what is expected of the other as a spouse and partner and you're both substantially on the same 'page' before taking the plunge, on a deeper level than just 'you two look great together' or being very compatible in bed.
