The issue isn't whether low time pilots should be at the controls. Your every day B737 line pilot is not the Boeing test pilot trained to respond immediately. If both Ethiopian Airlines pilots were "high" time, then who would you blame? The issue is Boeing has potentially (and perhaps knowingly) made a defective product and didn't properly notify and train their customers. Even if every 737 MAX line pilot was the Chuck Yeager of the skies, it doesn't absolve Boeing from making a defective product. The MAX is still defective. This is why the FBI is getting involved.
