In the Lewis Dual Sector Model of development, the 'Turning Point' occurs when the surplus labor in the traditional agricultural sector is completely exhausted, forcing the modern industrial sector to raise wages to attract further workers.

Answer: True

Arthur Lewis theorized that developing economies have an unlimited supply of surplus labor in subsistence farming, allowing the industrial sector to keep wages artificially low and reap massive profits for reinvestment. The 'Lewis Turning Point' is the critical milestone where this labor surplus dries up. Beyond this point, wages must rise across the entire economy, marking the transition to a mature, developed economic structure.
