It's knowable that the situation in the US will be comparably bad to what we're seeing in other countries. The original comment suggested that it'll be particularly bad in the US, and I think it requires a lot more than deduction to figure that.
I think you misread what the person I was respond to said.
In any case, I also disagree that it takes much to know that the US is going to suffer particularly bad. If people don't have job security, they aren't going to stay home. If people don't have health care, they won't bother trying to access it. This will help spread the disease faster than the health care system can handle it. Furthermore, given poor education levels and (justified) distrust of the government, in most of the country, compliance is going to be low anyway.
Time will tell.
