Very interesting ideas concerning polygyny. I fully support it. Polygyny is the Creator's Idea before STATE corporations existed. A man can possibly become to powerful to be controlled by the STATE, therefore,. the reason for the STATE to ban a man from having multiple wives, but private Contracts can't be banned, so says the constitution.
Not too many moons ago, a woman didn't have too much say in who she married, her father had that say, but, of course, that was when fathers was still respected by the family and television had not appeared on the scene. At that time marriages was arranged for bloodlines and inheritance. Today, bad is good, and good is bad, that's our problem.
Pursuant to all I can find concerning what the Creator says about being an employee, don't do it, unless you get paid every evening. A man is supposed to learn a trade to support his family, whether he's a farmer or an engineer. The increase a family makes is not supposed to be calculated in fiat currency, but in land, wheat, corn, beans, honey, and oil, etc. All wealth comes from the ground. If a man has enough land, and enough family to produce the crops, he can become very well off. The land produces a huge increase when properly handled. Consider, how many grains of corn is on 1 ear of corn, each grain will produce at least 2 more ears of corn, you can't make that kind of increase being an employee.
One man alone, cannot tend, and preserve what 1 acre of land will produce, but the man and one wife can easily do that, but that 1 acre of land will produce more food than 5 or 6 people could possibly use. A man and 2 wives could easily tend and preserve the produce from 2 acres of land which would be enough for as many as 12 people. Consider the offspring that would eventually be extra labor, as time goes by the family would be well off. That's what the Creator of the whole universe figured out a long time ago, He put man in a garden, not in a house.
