Economics Learning - March 12, 2026

Topics Covered

1. Internal vs External Debt

• Internal debt = Government owes money to its OWN citizens/institutions
• Government issues bonds → citizens/banks buy them → government pays back with interest
• ~80% of India's debt is internal (considered a strength)
• Safer because: paid in local currency, interest stays in economy, creditors won't flee

2. Why Does the US Have $34T Debt?

• Government spends more than it collects in taxes
• Major spending: Military ($850B), Social Security, Medicare, Interest ($1T/year)
• Countries buy Treasury Bonds because US is safest investment on Earth
• US has never defaulted

3. Why USD is Still the Benchmark

• Post-WW2 Bretton Woods agreement
• Oil traded in dollars (petrodollar)
• No real alternative (Euro/Yuan not trusted enough)
• Network effect - everyone uses it so everyone keeps using it

4. How Countries "Hold" US Debt

• Treasury Bonds = IOUs
• Japan holds ~$1.1T, China ~$800B
• They earn interest, can sell anytime
• Mutually assured destruction - selling hurts everyone

5. US Taxpayer Power

• Can't opt out of specific spending
• Only power: vote, protest
• Military-industrial complex deeply entrenched
• Both parties support military budgets

6. Tax Loopholes for the Rich

• Capital Gains vs Income: Work = 37% tax, Investments = 20% tax
• Buy, Borrow, Die: Own assets → borrow against them → die → heirs inherit tax-free
• Carried Interest: Hedge fund managers pay 20% instead of 37%
• Offshore Profits: Apple had $250B parked overseas at ~2% tax
• Real Estate Depreciation: Deduct "declining value" while property increases

7. Taxing the Rich (Bernie Sanders/Zohran Mamdani proposals)

• Wealth tax: 2% on $50M+, 8% on billionaires
• Tax capital gains as income
• Close step-up basis loophole
• Estimated revenue: $4.5-5.5 trillion over 10 years
• Would cut deficit by ~25%, not solve debt entirely

Key Takeaways

• Debt isn't always bad if you can pay interest and people trust you
• The rich pay lower tax rates than working people due to legal loopholes
• Average citizen has little say in how taxes are spent
• System is designed to maintain military dominance
