Have you actually looked at any data? Say the all-cause data for England and Wales (which I have going back to wk31, 1999):

What happened in England and Wales in Spring 2020 that caused an unprecedented* spike in deaths which coincided with COVID-19 being mentioned on the death certificate?
What happened in winter 2020-21 which had the worst week this Century, except for spring 2020?
This four-plot shows weekly numbers on the top, and cumulative along the bottom, raw numbers on the left and excess from a baseline of the median for the week number for 1999-2021.
The year runs from wk31 to wk31, which also manages to split out the first and second waves into 2019-20 and 2020-21
Note how the second wave is almost as bad as the first as far as excess deaths are concerned (easiest to see in bottom right plot)
There are many countries for which this looks similar, including the US and Europe as a whole. Some countries with decent approaches haven't been affected so badly.
