Everyone is allowed to air his or her opinion, but the opinion made by OP seems baseless to me, I wonder if the richest man on earth did not get married
If you decide to follow such idea you might end up being poor that you are afraid of or get rich and lack lots of importants Things in life, I doubt OP is doing all what he mentioned
if the richest person is not married then that will stop his offspring and will stop his wealth, it is better to get married and be able to get children who can be made offspring and your wealth will still be there because it will continue your business.
