So far, we have only seen a few civilian jet transports with high wings. All of them BAe 146, Do 328JET, seem to be regional jets. Yet military jet transports are almost completely high-wing. Why aren't we seeing high-wing large jetliners?

Some advantages of high wings:

* shorter landing gear
* easier access to the fuselage
* a better location for the center-of-thrust.
* better stability
* better ground clearance for upcoming high-bypass turbofans. Lack thereof caused the design changes that ended in 737 MAX crashes
* [Increased flap efficiency](https://aviation.stackexchange.com/a/77938/45534)
* better able to take advantage of strut-bracing, if any.

Some disadvantages:

* less efficient location of landing gear. (probably not mounted on the wings)
* more likely to tailstrike
* passengers may mock
* belly landings could be tricky
* water landings may be [even more tricky](https://aviation.stackexchange.com/a/78553/45534)

I don't know how these pros and cons add up though. Can someone give some more info?
