Yes, they are bought cheaply. Bargain-basement girls don't get far in life. They will wake up some day in the future and wonder where the years have gone. They will look in the mirror, and an older woman will look back. Their biological clocks will be running out, and there won't be much hope in their future.
Are all non-virgins who've yet to be married 'bargain-basement girls'?
You are a little too wound up in your rhetoric. As with many things, some are and some aren't. All kids that start off with a wild streak do not end up in the bargain basement.
