I'm sure you have not done enough research on the other areas that you spoke about. So no need to address that.
You don't want to "address" the other areas specifically because you can't actually refute, dismiss or actually challenge any of the facts that I previously presented below.
Wrong! Prenuptial agreements aren't 100% iron clad, can be contested after the fact & there is a alarming, growing trend taking precedent which show many pre-nups are actually being over-turned.
Wrong again! You'll actually spend a lot less money overall without a wife as it's one less person involved in your financial affairs who potentially can steal or siphon your money or the assets you've accumulated via actual theft or divorce. Also some wives don't work or have jobs, so in this case you are actually paying to feed, clothe, shelter, insure etc another person as well. The majority of men who get married based on financial reasons are those who can't earn a sufficient or substantial amount of money on their own & that have to rely on another person to help them pool money or other resources together to maintain a certain lifestyle. Even with the rate of divorce today, your spouses life insurance policy, which was once a key component to passing down wealth to children is in jeopardy now.
However single parent households just do not have the resources to pass on to offspring. rarely are they homeowners rarely do they have the funds to invest into retirement or insurance policies. It is about 2 parent households. Marriage ensures the greatest success if children are involved. We got all of these people here talking a having children but being against marriage. A 2 parent household sets a child up better for succes.
You don't need to be married to receive all of these attributes, as you can be in a long term,stable relationship & have children with your significant other (female) while achieving the same benefits you've mentioned with less short/long term risks & future uncertainty as a man if the relationship goes sour or doesn't work out.
