Depends on how you define value. From a financial and health perspective I'd say they are obviously -EV. From a happiness in life perspective I'd say for some they are very much +EV and for others less so. I'm not so sure about marriage though. True there is additional income but you also need twice as much of everything, not to mention the crap you don't need that she buys anyways. I guess it comes down to how you define "value".
