How should the balance between human capital and financial capital influence asset allocation over an investor's lifecycle?

Human capital (the present value of future labor income) is the largest asset most people own early in life. Treating it as part of the total wealth portfolio fundamentally changes optimal asset allocation.\n\nTotal Wealth Framework:\n\nTotal Economic Wealth = Financial Capital + Human Capital\n\nA 25-year-old engineer earning $95,000/year with 35 years of stable employment ahead might have:\n- Financial capital: $50,000 (savings)\n- Human capital: ~$1,800,000 (PV of future earnings at a reasonable discount rate)\n- Total wealth: $1,850,000\n\nFinancial assets represent only 2.7% of total wealth. The 97.3% human capital component dominates the allocation decision.\n\nThe Bond-Like vs Equity-Like Distinction:\n\n`mermaid\ngraph LR\n A[\"Human Capital
