Because we test more
We have more total tests, but countries like the UK have greater per capita testing than the USA. If their health system was even remotely as good as the USA's, the UK's case-fatalities should be similar to the USA, instead of being nearly 5 times the USA.
UK testing per million: 277,774
US testing per million: 203,940
