There almost certainly will be another surge, although (hopefully) not as large as the last one.
In addition to an older population, death rates are increasing also because Americans are living less healthy lifestyles.
I respectfully suggest that no mater which way the numbers
@CAV has quoted are going, we all have to recognize that COVID certainly has killed hundreds of thousands of Americans. We can quibble about the specifics. Doctors, administrators, and politicians are not perfect. They make mistakes and have agendas, just like everyone else.
But whether it's 100,000 or 1,000,000 or somewhere in between, hundreds of thousands have died from COVID.
I agree that states with loose mask rules have roughly the same results as states with strict mask rules. To me, this suggests that some of the more extreme measures have little effect.
However ...
You're missing where mask rules really are enforced within the United States - at the private sector level. Most (all?) national chains still require masks to enter their stores. Most (all?) large corporations are enforcing mask wearing. Day-to-day, these are where most people interact with other people.
Of course, we also have most universities and schools still enforcing masks as well, another place where people interact in large numbers.
As we've seen with the latest post-holiday surge, when people gather together in settings where masks are not worn (e.g. homes), outbreaks occur.
My wife told me (anyone else read this?) that cases of the flu are way down this year. If true, then I strongly suspect this is because of mask wearing, social distancing, extra cleaning, etc. work.
If these precautions reduce the spread of the flu, then it is logical that these same precautions reduce the spread of COVID.
