Why not check up? Why not improve or replace what's been the norm if it means to have a better army or military as a whole?

Checking up is frowned up but why not? Multiple thoughts come to mind when I think about the interactions between joes and NCOs.

Respect your chain-of-command...Why not respect everyone mutually?
Never check up...Should leadership remain unchecked if your NCO's leadership doesn't notice it?

Those are just two examples of countless I'm sure can be mentioned. Is the Army (or military as a whole) so stuck on many norms/traditions that we do not consider improvement among ourselves within the service? This is not to throw shade to those before me or or currently above me in rank. Overall how do send the message of improving our respect for each other regardless of rank or position?
