You can just look at the absolute number of deaths in the US versus pre-pandemic deaths (take a look at the table I posted in another reply) to see that covid and knock-on effects has substantially increased average number of deaths in the US.

This isn't someone just jiggering the stats, unless you think they are able to fake more than 500,000 deaths than we had in the previous 5 years of data shown by the table (table covers deaths from 2015-2020).
