Where the indentured servants of generational gone by equivalent to bonded labor?

Inspired by Richard Fletcher's question, I have the following comment. I recall what I took as a respectable study of indentured labor in (as I recall) 19th century Thailand which contrast rather sharply in tone with the conclusions about contemporary bonded labor in this video. In the video, bonded labor is treated as a "problem" requiring a "solution." In the study that I recall, indentured labor was reported to be a widely practiced strategy for rural families in Thailand. I believe that the practice was for a family to indenture one or two of its children or young adults for fixed periods in order to raise capital to invest in improving irrigation infrastructure for rice lands. I believe that the strategy was was reported as often successful in improving family welfare. This may have been an article based on David Feeney's doctoral dissertation research.
