Non-PRO English to Spanish Bus/Financial

This is the definition but I cannot find an equivalent in Spanish: The bonded laborer system is really the modern form of slavery, in which one cannot choose his or her location or type of employment. It is often caused by debt, or when a person, or his father, or grandfather, borrows a small amount of money from a landlord or master and then becomes bonded forever. This affects adults as well - men and women - and it is often related to caste; you will never see a Brahmin bonded laborer.
