For the first few centuries of America's existence it was common for Europeans to earn their boat-fare by agreeing to work for seven years for the person who paid their transportation fee.

We still have indentured servitude because it is very effective.
We have very generous immigration policies for overseas doctors who are willing to work in rural communities in America. These tend to be five-year terms. But they are indentured servitude nevertheless.
We have the same policy for teachers. They can have their college loans forgiven if they serve three years in a rural community. Again, this is indentured servitude.
It works. It is a voluntary relationship.
It is time that we stop thinking of indentured servitude as a negative. It isn't.
