Tariffs do generate government revenue but tend to raise prices on imports, causing at least a one-time increase in price levels, which can be inflationary; claims of entering a 'golden age' due to tariffs overlook economic complexities and historical context.
Tariffs are not inflationary. Tariffs are a massive source of revenue. We are truly entering a golden age.

What the Evidence Shows
The input contains three main assertions: first, that tariffs are not inflationary; second, that tariffs are a massive source of revenue; and third, that we are entering a golden age. Regarding the inflationary impact, economic research indicates that tariffs act as trade barriers that raise the prices of imported goods, leading to higher costs for consumers and businesses. While tariffs may cause a one-time increase in the overall price level, they do not necessarily cause sustained inflation (a continuous rise in inflation rates).
This nuance means tariffs can be inflationary in the short term but are not the sole driver of ongoing inflation.taxfoundation.orgtaxfoundation.orgTrump Tariffs: The Economic Impact of the Trump Trade War

However, this revenue comes at economic costs such as reduced trade efficiency and higher consumer prices. Lastly, the statement about entering a 'golden age' is more subjective and historically contested. While some proponents link high tariffs to past periods of industrial growth (the so-called Gilded Age), historians and economists note that era also involved significant poverty and inequality.
Moreover, modern analyses caution against simplistic comparisons and highlight that tariffs alone do not guarantee broad economic prosperity.aei.orgaei.orgWhy America’s Golden Age of Tariffs Was Really the Golden Age of Immigration -... Therefore, while parts of the input have factual basis (tariffs generate revenue), the overall framing is misleading because it downplays the inflationary effects and oversimplifies complex economic outcomes.
