It's not clear that it has been. Singapore was at that point, until a sudden spike in new cases overwhelmed them and they had to lock down. South Korea just re-closed their bars and pushed back school reopenings, because a single guy started a cluster of 80 cases and they don't trust their contact tracing to handle that many. Taiwan and Vietnam are either lucky or have better strategies than simply "do a lot of contact tracing", but in either case it's not obvious that other countries can replicate their success.

It's not eradication, but it's a much more fine-grained tool that lets some of the economy open back up in a safer way. It's what we should be aiming for everywhere.

The US might not be able to do quite as well, but it feels like we're barely even trying.

Agreed. But everywhere I know of, including Texas, is indeed aiming to do lots of contact tracing so opening up the economy is safer.
