If I walk into a room of people with the black plague, I'm concerned about every single person in that room giving me the disease not just the people of my age bracket.

That's the chance of infection.

This same idea is used in mask policy and is used with herd immunity calculations and all over epidemiology to be honest.

I'm really sorry that you have to do mental gymnastics to shoehorn this subject into your narrative.

Have a good day!

I wasn't the one who brought up age brackets, you were ("infected 50 year olds"). But here's the calculation for the entire US population.

Total number infected until early November 2021: ~37 million [1]

Total population of the US: ~329 million

Infection percentage so far in pandemic: 11.2%

"Chance of infection" (per annum): ~7%

See above why this is an absurd extrapolation that nobody with any brains would take seriously. In the long run, pretty much everybody will get Sars-Cov-2. It's an endemic disease.
