Bullshit, and it's the domestic consumer price index, in particular, that sets prices and no foreign entity either:
U.S. economy accelerated at a robust 6.4 percent rate last quarter
Growth in the current April-June period is expected to be faster still, potentially reaching a 10 percent annual pace or more.
Powered by consumers, the U.S. economy grew at a brisk 6.4 percent annual rate last quarter — a show of strength fueled by government aid and declining viral cases that could drive further gains as the nation rebounds with unusual speed from the pandemic recession.
Thursday’s report from the Commerce Department estimated that the nation’s gross domestic product — its total output of goods and services — accelerated in the January-March quarter from a 4.3 percent annual gain in the final quarter of 2020."

The Biden Boom: Economic Recovery in 2021
President Joe Biden took office one year ago amid one of the worst economies in generations, but the U.S. economy has since made tremendous progress toward recovery, and workers are benefiting.
January 20 marks one year since President Joe Biden took office: It’s time to take stock of the historic economic boom under his leadership.
Though the United States faces serious economic challenges amid the ongoing global pandemic, 2021 was an extraordinary year of economic growth and recovery. The country saw record job gains and an unprecedented drop in unemployment. The economy likely grew faster than in any year since 1984, as measured by real gross domestic product (GDP). In 2021, the economy not only regained all pandemic-related GDP losses—it also surpassed pre-pandemic levels. Despite elevated inflation, Americans’ disposable incomes were higher in 2021 in real (inflation-adjusted) terms than they were in 2019 and 2020. Additionally, by many important measures such as savings and bank balances, Americans are more financially secure. The United States also made dramatic progress in lowering its exceptionally high rate of child poverty."
