Hmm...I think you're under the impression that we're not all going to get this virus. Everything we're doing now is just to slow the virus so we don't all end up in the hospital on the same day. We're all going to get it in the next 18 months just like the way we get the flu when there is an outbreak. Also not all of us are going to be completely out of commission. Some of us will just have mild symptoms before it goes away.
What's your point? Mktrader was arguing against the death toll, not death rate https://www.worldometers.info/coronavirus/
I recall reading that most of the taxes are paid by 45 to 55 age bracket. Intuitively, it makes sense since that's the age of peak earnings in majority higher-income people. People who continue increasing their incomes past that age are an exception, not a rule.
tax bracket is not age dependent.. it's income dependent... so if the 80yo dies, his heirs get the money and will keep paying.
Steve Jobs wife isn't giving the heirs money. Buffet isn't giving heirs money. Gates is also throwing all his money out the window. So instead of paying billions in taxes on the interest they make on their money, it will all be donated to tax exempt charities and vanish like a fart in the wind.
