The summary

Claim that the pre-pandemic economy was the best in world history is unsupported by standard metrics.

The fact-check

GDP growth, wage growth, and job creation during the 2017 to 2019 period were similar to the final years of the Obama administration and did not exceed multiple post-WWII booms.

Truth on the record

On virtually every economic measure - real GDP growth, unemployment declines, wage growth - the pre-pandemic economy was strong but not unprecedented.
