You wot m8?
You are drawing conclusions based on developing events, therefore data is gonna be skewed. Two of those countries have case barely a month old, and of course people are dying of the disease faster than they are recovering. And the US, is well, the US. First class sh1t-show of a health system combined with a leadership that values stock prices higher than people's lives.
Look at South Korea. One of the first countries affected outside of China, of the current 9332 cases, 4528 have recovered, 139 have died. 3% mortality rate, in-line with the WHO's initial estimates. Sure, there is still plenty of time for that to vary, but it is certainly trending that way.
Edit: corrected my poor reading of the data timelines
