Both Harding and Hoover realized something more than an agreement was needed, but Congress was slow to act, not imposing radio regulation until 1927.[154]
Harding also wished to promote aviation, and Hoover again took the lead, convening a national conference on commercial aviation. The discussions focused on safety matters, inspection of airplanes, and licensing of pilots. Harding again promoted legislation but nothing was done until 1926, when the Air Commerce Act created the Bureau of Aeronautics within Hoover's Commerce Department.[154]

Harding's attitude toward business was that government should aid it as much as possible.[155] He was suspicious of organized labor, viewing it as a conspiracy against business.[156] He sought to get them to work together at a conference on unemployment that he called to meet in September 1921 at Hoover's recommendation. Harding warned in his opening address that no federal money would be available. No important legislation came as a result, though some public works projects were accelerated.[157]
Within broad limits, Harding allowed each cabinet secretary to run his department as he saw fit.
