Our modern concept of two people raising their children under one roof grew out of feudal necessity. The absolute minimum number of people necessary to maintain a plot of land during the Middle Ages was two. As the lord of the land wanted his serfs to "be fruitful and multiply" (thus multiplying the wealth of the lord), it was necessary that one of the two people be a man and the other a woman. Serfs were paired until death did them part. Love had nothing to do with it. (The only people who had time for such luxuries as love were those in the royal court—hence the term courtship.) The man tended the land all his waking hours, and the woman tended the house, livestock, and children. Even if a husband and wife hated each other, all they had to do was wait a little while: what with disease, war, childbirth, and an average life span of about thirty-five years, most marriages lasted less than five years. The departed partner was immediately replaced, and the system continued—not because the serfs liked it, but because it was economically viable for the aristocracy.
The system worked so well and the aristocracy was so pleased, they got the church involved. A marvelous theology developed (marvelously useful to the landowners): work hard in this life (which is but a blink in the eye of eternity), serve your lord (who represented the Lord), and you will have paradise for all eternity—and that's a long, long, time Mr. and Mrs. Serf. Rebel against the lord (Lord), and you will spend all eternity (which is a long, etc.) in hell. Be true to your spouse (not being true to your spouse would take valuable time away from essential serf stuff), work hard, and eternal paradise will be yours.
When it comes to professional relationships, the law recognizes just about every kind. In business, there are sole proprietorships, limited partnerships, corporations, and any number of other government (and, more important, IRS) recognized relationships. The laws and customs are neatly in place for mergers, takeovers, creating, and dissolving professional relationships of all shapes, sizes, and durations.
Why is it, then, when it comes to personal relationships, there is only one legally recognized, community approved, IRS sanctioned relationship: one man and one woman promising fidelity until one of them dies? Only in this relationship—known as marriage—do people get the tax breaks, bank loans, realtor acceptance, and Welcome Wagon visits.
If business law had an equivalent to the laws concerning personal relationships, it would say, "If you're in business, you must have one partner, and only one partner, and keep that partner, until one of you dies." If this were the law, can you imagine the state of business in America? The same is true of the state of personal relationships.
If we allow people to follow their hearts (and what else should they primarily follow in romantic relationships?) and allow relationships the freedom to grow, dissolve, merge, and interact with the same legal freedoms and protections we give business, then everyone—including (and perhaps especially) those who want a traditional marriage—would be a lot better off.
