America's return to normalcy also brought what?

America's return to normalcy also brought "healthy frugality" and "renewed isolationism."

Explanation:

"Return to Normalcy" was part of Warren G Harding's campaign. He was the 29th president of the United States. According to him, the USA should return to normalcy by preventing wasteful spending and extravagance. For him, this was a healthy way of becoming frugal because it will lessen the tax burden on the people (income taxes). This will also bring about "renewed isolationism" on the nation, which will make the USA more advanced and self-reliant. He was also confident of bringing peace to the nation.
