It's far more complex than that. A better way to simplify it might be to say that for any given person there is probably 1% of the population (in the right age and gender group) that is suitable for a long term commitment. And it is not the same 1% for everyone.
I don't want to put words into your mouth, but the perception I (and others in this thread) are getting from you is you don't want to find a soul mate, you want to find a wife to 'manage your household' or do fulfill a similar role that has little to do with being your counterpart.
