Final answer:
The statement that a new and extremely rich financial class lobbied the government for less taxes on the rich is historically true, evidenced by the 1920s tax policies that favored wealthy individuals.
Step-by-step explanation:
The idea that a new and extremely rich financial class lobbied the government for less taxes on the rich can be considered true when observing patterns throughout American history. For instance, in the 1920s, the Republican-controlled Congress and White House enacted policies that significantly reduced the tax rate for the wealthiest Americans and protected US businesses with high tariffs, consequently raising consumer prices. Additionally, throughout various periods in US history, wealthy individuals and businesses have often sought to shape governmental policy decisions to their advantage—this includes lobbying for lower taxes on the rich and for policies that favor their economic interests.
