By what percentage did Harding/Coolidge cut taxes in their 18 month recovery from the Depression of 1921?

it wasn't Harding or Coolidge it was Herbert hoover who was directly responsible for the turn around as he was the commerce secretary and it was hoover who warned Coolidge of an economic disaster with the market but Coolidge failed to heed his warning which is what directly led to the market crash of 1928 and to hoovers ultimate election to the presidency of the united states
