Secretary of Transportation Pete Buttigieg (D-MI) said higher taxes on the wealthiest Americans could fund a national high-speed rail network.

This proposal links fiscal policy directly to infrastructure development, suggesting that wealth redistribution is a primary mechanism for modernizing U.S. transit. By targeting capital-gains and wealth taxes, the administration would seek to bypass traditional budget constraints that have historically stalled large-scale rail projects.

Speaking on the morning show "Rising" on Aug. 4, 2026 [1], Buttigieg said the revenue generated from these tax increases would allow the government to invest in high-speed rail. He said such a move would make the United States a fairer country while providing the financial resources required for major infrastructure builds [2].

"If we raise taxes on the wealthiest, we can finally build the high-speed rail the country needs," Buttigieg said during the interview [1].

High-speed rail has remained a point of contention in U.S. policy due to high initial costs and land-use disputes. Buttigieg said the current tax structure does not provide sufficient capital to meet these needs. He said that shifting the tax burden toward those with the most assets would create a sustainable funding stream for the project [2].

"Higher taxes would make America a fairer country and give us the money to invest in infrastructure like high-speed rail," Buttigieg said [2].

The proposal focuses on using wealth taxes and capital-gains taxes to bridge the funding gap. This approach targets the accumulation of assets rather than just annual income, a strategy intended to capture revenue from the nation's highest earners to support public works.

“"If we raise taxes on the wealthiest, we can finally build the high-speed rail the country needs."”

The proposal represents a strategic shift toward using progressive taxation as a direct funding tool for specific infrastructure goals. By tying high-speed rail to wealth taxes, the administration is framing transportation modernization not just as a logistics issue, but as a matter of economic equity and fiscal reform.
