Maybe a better question is: "Will I or my children ever become indentured servants'.
For a lot of people in the world today, slavery is a fact. It is probably closer than you think. Not too many years ago my family had a reunion dinner at a local chinese resturant. As I went to pay the check I chatted with the girl at the register. She was very young - mid to late teens, and younger than my daughters at the time. You could tell that she was trying out her english on me by talking about more indepth subjects than what the bill was.
She told me that she was married to the cook, and that her mother lived in Bejing - she had a special calling card to call mainland China. She said that she and her husband worked seven days per week, and that they would do this for the next three or four years to pay off their debts....
We know quite a few Mexicans that have come across and work in almost indentured conditions - I guess they can quit and go some where else if they want too, so it is not quite the same, but it is a pretty tough row to hoe.
In India, the caste system has been outlawed - at least on the books, but millions of lower caste people work in virtual slavery all of their lives. There was a National Geographic article a couple of years ago about it..

And another article on slavery world wide:

I don't know that it would have to become common.... and truly hope that it doesn't. A voluntary indenturement would be one thing, but I don't think it is in the nature of slavers to ever grant freedom.
