Why is the cockpit of a civil aircraft not equipped with ejection seats?

First of all, the cabin is sealed and pressurized. Based on this principle, the aircraft has very high requirements for the structure of the aircraft, and no gaps are allowed. The setting of ejection seat needs corresponding ejection channel. Fighters can blow up the hatch cover above, while passenger planes have to blow up the hatch cover if they want to blow up. Moreover, there is an operating roof at the top of the cockpit, which may not have been blown out by the traditional "explosion hatch cover". Increasing the amount of explosives may directly kill the captain. Therefore, the cockpit cannot be equipped with ejection seats. This question can be simply answered from two angles: a. Subjectively, as a commercial airliner with hundreds of people behind it, if the courier parachutes to escape in an emergency, can you still trust this airline as a passenger? As the basic ethics of commercial aviation, in an emergency, the airport should escape after all the personnel are evacuated. B. Fighters not only have ejection escape systems, but also pilots are equipped with anti-load suits and respiratory maintenance systems, which can provide limited protection for high-altitude high-speed ejection skydiving. Imagine what would happen if a civil aviation pilot in a suit and tie ejected.
