Episode notes
Amendments Change Text, Not Just Interpretation
- Changing the Constitution requires both congressional approval and state ratification, making amendments slow and deliberate.
- John Streeter emphasizes that textual changes, not judicial interpretation, reshape national law permanently.
Why The Income Tax Became Central
- Progressives pushed for a federal income tax to make the wealthy pay a fairer share and relieve indirect-tax burdens on the poor.
- The 16th Amendment enabled a graduated income tax that dramatically changed federal revenue and policy over the 20th century.
Senators Became Directly Elected
- The 17th Amendment shifted senators from state legislature appointees to directly elected officials, reducing state-centered representation.
- John Streeter links this change to weakening states' influence and enabling national reforms like civil rights advancements.
