Damn, that is a tough question. I am thinking, that a working person, could not be on the clock 24/7. So you would have to hire at least 3 women, who could at least switch every 8 hours, but that would have them working 7 days a week still, and 56 hours each. But then, you would have to pay over-time for 16 hours each, for the 3.
I would go ahead, and hire a 4th. That over-time, would eat you up. And not giving a day off, could make for some dangerous situations, especially around "that" time of the month, if you know what I mean.
I would figure, at least $10.00 an hour, but you will have to pay taxes, workers comp. and Social Security. Unless, you hire an illegal alien.
Good points though, with a hire,
If they nag you, they can just hit the door. No alimony.
If they fail to perform their job duties, they are outta here.
You can demand that certain duties be done, in the way you want them. Without risking an iron frying pan to your head, in the middle of the night.
Lunch is on their own. My boss doesn't feed me.
I do think a wife would be cheaper, even though you do have the extras, of food clothes, etc. But the nagging, how much is NOT hearing that worth? You just can't put a price tag on peace of mind.
But the biggest problem, with a wife, that I see, is that, you can't be guaranteed of any work out of her what-so-ever. They could be like me. I crawl out of bed, around 10:30 am. Go downstairs, and expect to eat my maple cinnamon roll, that my husband bought for me fresh, before going to work. I get on the computer, for 2 hours, doing nothing constructive, usually take a shower, after Oprah. Get back on computer, and ask my husband what is for dinner.
So, I ask YOU. Would you rather pay, and get things done right, or take your chances, and get a wife like me?? Scary, isn't it??
