[190] The act increased taxes across the board, rolling back much of the tax cut reduction program Mellon had presided over during the 1920s. Top earners were taxed at 63 percent on their net income, the highest rate since the early 1920s. The act also doubled the top estate tax rate, cut personal income tax exemptions, eliminated the corporate income tax exemption, and raised corporate tax rates.[191] Despite the passage of the Revenue Act, the federal government continued to run a budget deficit.[192]

Hoover seldom mentioned civil rights while he was president. He believed that African Americans and other races could improve themselves with education and individual initiative.[193]  Hoover appointed more African Americans to federal positions than Harding and Coolidge combined, but many African-American leaders condemned various aspects of the Hoover administration, including Hoover's unwillingness to push for a federal anti-lynching law.[194] Hoover also continued to pursue the lily-white strategy, removing African Americans from positions of leadership in the Republican Party in an attempt to end the Democratic Party's dominance in the South.
