My statement, "most dramatic rise in unemployment," means something different.
While the Great Depression saw a much higher peak unemployment rate, the rate of change in April 2020 was the fastest one-month increase in US history.
I actually interpreted the phrasing of "most dramatic rise in unemployment the U.S. had ever seen" exactly to mean "it was even worse than the great depression in some ways". It seems too peculiar of a thing to say otherwise, especially when the great depression is like the main thing anyone would think to compare it to.
