What a pack of lies. Marriage allows expenses to be shared and usually results in lower tax rates. Nobody’s pre-marriage debts will change solely because of marriage. Children will add to expenses, but children without marriage will cost even more.
Yes. And more gets shared. Like reason and judgement. When we married, we both had nothing and built our future together. That meant thinking through finances and not wasting resources. Too many young people are careless and don't reasonably consider actions. Marriage made my wife and I smart about how we built a life together. And having children brought us good fortune, because we worked even harder for their sake. Almost fifty years together now, and its been great.
