This may not be the best legal answer, but here goes:
The white keys on the piano are represented on the staff (either staff, bass or treble) as line - space - line - space, etc.
So, with the treble, if you start with middle C, that is on a line. The space above it is D, the line above is E, and so forth.
Keep going and the C above middle is is on a Space, not a Line.
Keep that in mind, because it is on the Third Space up.
Now, go back to Middle C on the Bass Clef and go down. Once again, you are starting on Middle C which is on a line, and if you go down to the first C that is below Middle C, it is on a space. It is on the 3rd space down,
just as the C above middle C is the 3rd space up.
So, what you are saying is not accurate:
the Bass, or left hand scale read differently as far as what note is on what space or line?
The Bass is not different, what is different is that in both the Bass clef and the Treble clef the same note alternates from Line to Space as you go up or down an octave.
I too wish that it were different. Literally hundreds of attempts have been made to change or come up with something that does not do as you noticed, but none have stuck.
I suggest that you find what are called "Landmark" notes. Middle C is probably the most obvious one. Try learning the location of the C above it and the C below...they are on the 3rd space up, and 3rd space down.
Middle C is where most people start learning piano, and thus is a very familiar place on the staff, as are the neighboring notes. So learning where the C above and the C below are on the staff gives you another familiar landing place.
With Landmark notes, you can use them as reference points to find nearby ones. And eventually it will sink in, just like when you become familiar with a new city or building layout or computer program, it sinks in where things are.
