You do realize that if those death rates [0] hold up, when you take today's global population by age demographic and tally up how many people are expected to die within each age group, you get a total of 90 million dead.
Given that top epidemiologists are predicting 40-70% of adults will be infected this year, that would mean roughly 35 to 62 million people would die this year.
That sounds like a lot of people, but it's not likely to cause real, noticeable problems in society. I think there's a good chance that our reaction to the virus is more damaging than the virus itself.
If 40-70% of people will be infected this year and 35-62 million will die, that's 1-1.5% death rate. The average person will probably know a few people that die from it, but the average person probably knows hundreds of people. This is going to be similar to the number that die from car accidents or HIV, and neither of those have wrecked society. It's going to be sad, but probably won't change life as we know it, unless we let it.
Personally, I think we're all overreacting a bit, and the overreaction is what's going to cause the problems, not the disease. The Spanish flu caused problems, but that was ~10x deadlier than COVID-19. We all just need to worry less and be a little more proactive about visiting the doctor.

I would consider that a harrowing experience.
