Yes and no. Older people that don’t breed help raise younger people and increase their fitness. Or so the theory goes.

Probably doesn't matter much in first world countries.

Agreed. Especially with an average age of death in developed countries of around 78 years old.

I'd bet money the average age of death is drastically reduced after recurring Covid infections. If you consider it's a vascular disease, and the side effects that are reminiscent of trauma, repeated trauma leads to prematurely mortality. Thus, repeated Covid infections would in theory do the same.

In Northern European and England-offshoot nations, grandparents mostly don't help with raising kids.
If most people dying are 60+ it's not natural selection. Parents of minors are mostly in their 30s, 40s, and 50s.

“Raising kids” can be as small as babysitting for date night. Or allowing someone to borrow a car for a doctor appointment.
