Got me to thinkin' about what the best design for a short-haul jet airliner would be. Obviously one whose maximum landing weight is closest to it's maximum takeoff weight. Which current aircraft fit this criteria best and what desing features enable the landing weight to be closer to the maximum takeoff weight?
I think you're running with some assumptions that might not work here. There are tradeoffs involved with these kinds of decisions. They don't make the aircraft unable to land at MTOW by accident remember. In order to make the aircraft able to land at MTOW, you need a much stronger supporting structure to handle the forces of landing in a fashion that won't damage them. Beefier landing gear, beefier wings, etc.
The stronger you make them, the heavier they get. The heavier they get, the more effort you need to get them off the ground. The more effort you need to get them off the ground, the less useful cargo and passengers you can carry. The less useful work you can do, the less money the airplane makes. You can see how these kinds of decisions cascade, and factor into how sucessful a plane is at it's role. That's why airplanes aren't all designed the same way.
If you look at the design history of almost any jetliner, the decisions will revolve around the average range of flights, how many cycles they can fly, how much useful cargo there needs to be, and a host of other factors.
There are 10 kinds of people in the world; those who understand binary, and those that don't.
