To grasp modern economic growth, we must contrast physical assets with human capabilities:
| Parameter | Physical Capital | Human Capital | Human Development |
|---|---|---|---|
| Nature | Tangible assets (factories, machines, tools) | Intangible knowledge, skills, health of workers | Comprehensive human well-being, dignity & freedom |
| Separability | Separable from its owner (can be sold/rented) | Inseparable from the individual human being | Focuses on human fulfillment as an end in itself |
| Depreciation | Depreciates through physical wear & tear and obsolescence | Can be continually upgraded through lifelong education & health | Not an economic input; measures quality of life |
Human Capital vs Human Development: Human capital treats human beings as a means to increase productivity and GDP. Human development views human well-being, education, and good health as ends in themselves—every human has an intrinsic right to literacy and healthcare regardless of labor productivity.
