In reality:
"We" (not the U.S., not the U.K, not western civilization) are not on pace to have the highest all-cause mortality in the last 30 years.
This table provides the monthly mortality count for each month for many years:
data.cdc.gov
The CDC's numbers are always delayed a few months, but logically, you can determine how this year compares to past years. This year won't be higher than last year. So that crushes your claim already. Remember, recently, you said that this year was going to be X% higher than last year, and data easily refutes that. Hell, I lowered your claim in half and offered you $500k to wager, and you ran, because you realized that your claim was bogus.
Again, that table blows away your claim.
You didn't provide any data proving your claim. A CEO of a funeral home company predicting something is not the same as your claim. More, he didn't even claim what you did. You were simply trying anything - even if it didn't back your claim - to help as a last gasp effort.
You failed.
