Step 1: Understanding the burden on future generation.
The burden on future generations is typically associated with the accumulation of debt. When the government borrows money today, it must repay that debt in the future, which creates a financial burden for future generations. Expenditure and taxes can be adjusted in the short term without necessarily affecting future generations.
Step 2: Analyzing the options.
(A) Expenditure: While high levels of government spending may affect future budgets, it does not directly place a burden on future generations unless financed by debt.
(B) Tax: Taxes affect the current population, but they do not typically create a future burden unless there is a significant imbalance in tax policy.
(C) Debt: Correct. Debt creates a future burden because it must be repaid, often with interest, by future generations.
(D) All of these: This is incorrect, as only debt creates a direct burden on future generations.
Step 3: Conclusion.
The correct answer is (C) Debt, as debt creates a financial obligation for future generations to repay.
