You are ignoring the passage of time. This virus will eventually spread until at least half of our population is infected unless something is done to stop it.
In 2009-10 the Swine Flu infected 60,000,000 Americans. 18,000 or so died. Well over 200,000 were hospitalized.
Fortunately, Swine Flu had a very low fatality rate. We may not be so lucky this time.
I am pretty sure I am not ignoring the passage of time. As someone who treated swine flu I can tell you what I say then is much worse than what I see now. So before you make a statement that is untrue do a little research.
The number of people infected is probably vastly under-reported, you have a lot more people in the US in the 20-30 age range that 70-100, yet only a minuscule amount of REPORTED cases from them, but there are undoubtedly lots and lots of them asymptomatically spreading.
And that is mostly good news. Wouldnt surprise me at al. If half the kids in the USA are carriers. They touch everything they like everything the hug everyone, (Im not complaining, I have a dozen fantastic grand-squirts), I honestly think that herd immunity is happening very quickly. 10% of the population may have had it already, and if so, it will be 90% by May.
South Korea may be doing well because at the beginning, they had a big number of seed cases existing in very social people, and so lots and lots of spreaders almost immediately, which makes it likely it has gone through the population much faster
