I think that you are sort of comparing apples & oranges here. Concorde was a clear accident caused by FOD. There was nothing inherently wrong with the design of the aircraft that some Kevlar couldn’t sort out.

Here you have an aircraft whose certification was grandfathered off the older design and that the manufacturer didn’t even see fit to tell it’s customers about the MCAS system.

Then you have the fact that blame is being being deflected onto the pilots of the aircraft that crashed just because the respective airlines involved are not considered to be first world airlines, so there must be something wrong with their training or capability.

Finally, the FAA has outsourced critical safety functions to the manufacturers, so there is no independent checking of the airworthiness of the aircraft involved.

None of this was present in the Concorde accident.
