Yes, the US government has failed.

Yes, the US is ahead of many nations in raw testing numbers, and in terms of tests per capita (although some do beast us in terms of per capita testing).

Indeed, I mentioned this the last time you posted a similar statement. Here's the graph of test positivity rate for a number of nations: https://ourworldindata.org/grapher/covid-19-daily-tests-vs-d...
So why is test positivity rate important? Because test positivity measures how well you're controlling the outbreak. New Zealand doesn't need to test the entire nation regardless of symptoms. The fewer infected people there are in the population, the less value you get from testing random asymptomatic people. But, if all your tests are positive, it means that you aren't using any on asymptomatic people. You need to test asymptomatic people to prevent asymptomatic/community spread and as part of contact tracing. If you can't do those things, you'll end up with unquarantined infected people spreading the virus.
So as test positivity goes down, even as testing rate goes down, you can know that you have a smaller number of cases overall. (and that your reinfection rate is <1).
> Clearly it has absolutely nothing to do with how close a country is to being able to test a particular proportion of the population on a regular basis regardless of symptoms.
So while you're correct here, this isn't actually the goal if you can trace reasonably. Which, like, the US can't because too many people are infected. So insofar as controlling things are, the US's case numbers are, to use your words, "catastrophic", while many other nations' are not.
