I would dare to suggest that you need to take a pragmatic and realistic look at the situation before getting all emotional.
Smallish regional airports for example = not a lot of ramp space = use the concrete that they do have to cater for the
revenue-making commercial traffic = bye bye unneeded runways.
GA does not pay it's way when compared to commercial in a scenario where it has to be one or the other (limited staff / facilities / space etc etc). As a profit making company, what do you expect them to do?
It is not "nice" it may seem unfair and it is not friendly but it makes cash sense.
The bottom line = Max PROFIT for min cost!
Now as for the GA can pay for facilities that it does not need question - Mode S as an example = there is a whole new argument
