Rostow's modernization model outlines 5 stages of economic growth: 1) Traditional society focused on subsistence and barter 2) Transitional society with specialization, surpluses, and infrastructure 3) Take-off stage with industrialization, growing investment, and regional growth 4) Drive to maturity with diversification, innovation, and less reliance on imports 5) High mass consumption oriented toward consumer goods and services The model is criticized for being too mechanistic, based only on developed countries, and assuming all countries must adopt American-style mass consumption as the endpoint of development.
