Alexander Hamilton argued that a united economy was essential to a functioning government. Nearly 240 years later, his questions about taxation, trade, and public responsibility remain familiar.
A government can promise security, prosperity, and stability. Delivering on those promises, however, requires something considerably less romantic than revolutionary ideals: money.
In Federalist No. 12, “The Utility of the Union in Respect to Revenue,” published November 27, 1787, Alexander Hamilton turned his attention to a practical problem facing the proposed United States. How could a national government function effectively if its member states maintained separate commercial policies and revenue systems?
His answer was economic unity.
Hamilton believed that a stronger union would encourage commerce, simplify tax collection, and provide the federal government with a more dependable source of revenue. Without that coordination, the young republic risked creating a government with responsibilities it lacked the resources to fulfill.
Thirteen States, Thirteen Opportunities for Trouble
Under the Articles of Confederation, Congress lacked independent authority to impose taxes directly. Instead, it depended heavily on contributions requested from the states, an arrangement that frequently left national obligations underfunded.
Hamilton saw another problem in the prospect of states operating as separate commercial jurisdictions.
With extensive coastlines, interconnected waterways, and relatively easy movement between neighboring states, enforcing different import duties would be difficult. Merchants could redirect goods through jurisdictions with lower taxes, undermining revenue collection elsewhere.
A unified system, he argued, could reduce opportunities for evasion while making commercial regulations more consistent.
The argument was straightforward: collecting revenue becomes considerably more difficult when neighboring governments are working from different rulebooks.
The Politics of Paying for Government
Hamilton also understood that Americans were unlikely to embrace aggressive direct taxation.
Taxes on land, property, and agricultural production were politically sensitive. Import duties, by contrast, offered a way to generate revenue through commercial activity.
He considered commerce particularly valuable because its growth could increase both private prosperity and government income.
There was, however, a broader assumption underlying his argument: economic activity and public finances were connected. A government needed resources to operate, and those resources ultimately came from the society it governed.
Hamilton was not proposing the modern federal tax system. His discussion reflected the economic conditions and political limitations of the eighteenth century, when customs duties played a much larger role in federal revenue than they do today.
An Old Debate in a Modern Economy
The United States eventually developed a far more extensive system of federal taxation, spending, and financial regulation than Hamilton described.
Yet the relationship between commerce and public revenue remains central to contemporary debates.
Tariffs, taxation, interstate commerce, infrastructure funding, and federal spending all involve questions about how governments raise money and distribute financial responsibilities.
The disagreements are substantial. Some favor lower taxes and more limited government expenditures. Others emphasize public investment and the need for sufficient revenue to maintain services and meet national obligations.
Hamilton’s essay does not settle those disputes. It offers a historical perspective on why the financial structure of government matters in the first place.
It also invites a question that receives less attention than debates over individual tax rates: What happens when a government accepts responsibilities without establishing dependable ways to finance them?
What Hamilton Leaves Us With
Federalist No. 12 is less concerned with grand declarations of liberty than with the machinery required to sustain a nation.
Hamilton recognized that political independence did not automatically produce financial stability. The proposed union needed institutions capable of supporting its responsibilities, including the collection of public revenue.
His argument was ultimately about capacity: whether the government being created would possess the practical means to carry out its assigned duties.
Nearly two and a half centuries later, Americans continue debating what government should do, what it should cost, and who should pay.
Hamilton’s contribution was a reminder that those questions cannot be separated quite as neatly as political rhetoric sometimes suggests.
After all, even a republic built on revolutionary principles eventually has to balance the books.
