marriage was designed to promote a healthy stable environment to raise children. It was also good for the parents, but the point was the chidren.

So lots of breaks were given to married people, and bachelors took up the slack in many different ways to protect and help support families.

I always regarded homosexuals as de facto bachelors, since they cannot naturally produce children.

maybe we should only regard married couples with children as legally married in civil law? This way married heterosexual couples without children have to contribute as much as the rest of the bachelors, to make everything more fair?
