Taxes are paid in the sweat of every man who labors.

The line frames taxation not as an abstract accounting matter but as something ultimately borne by human effort. By saying taxes are paid in “the sweat” of laborers, the speaker emphasizes that public revenue comes from real work and sacrifice—time, energy, and productivity—rather than from impersonal institutions. The implication is ethical as well as economic: because taxes represent the converted labor of ordinary people, government has a duty to levy them fairly and spend them responsibly. In a Rooseveltian register, it also supports the idea that public policy should protect workers and ensure that the burdens and benefits of the state are distributed justly.
