GA paying fair (fare?) share

With regard to subway riders there is only one distinct group; subway
riders. With regard to civil aviation there are two distinct groups;
airlines and GA. That's why your subway analogy doesn't work; you treat
one
part of the group, you and your relatives, differently than the rest of
the
group.

Any group we care to delineate is "distinct" in some respect or other
(including the arbitrarily delineated group in my analogy). How does the
degree of "distinctness" of a given group bear on the question of whether
marginal cost is the the right measure to use when assessing fees for that
group? It seems to me that you're arbitrarily requiring the group to be very
"distinct" just because that gives the answer you want to arrive at
regarding GA fees. The wider public, which does not share our incentive to
invent reasons to keep GA fees low, will not be persuaded that the degree of
the group's distinctness is relevant.

In what meaningful way are you and your relatives distinct from other subway
riders?

Nobody should be required to pay for things they do not use.

I'm not requiring them to be distinct, they simply are distinct. Do you not
agree? Does a Cessna 172 have the same runway needs as a Boeing 747?

We're not inventing them, were simply pointing them out. I think the wider
public can see the difference. It's easy to put it in terms the non-flying
public understands. Most of them operate motor vehicles. How many Toyota
drivers believe they should pay the same fees as Peterbuilt operators?

How does that reply address the question it's replying to? In essence, the
question has to do with how we quantify the "things they use"--in
particular, is the marginal cost the right measure? You're proposing that
it is the right measure for "distinct" groups, but not for groups that
are not very "distinct" (such as in my analogy). What I'm wondering, and
what you have yet to address, is why you think a group's "distinctness" has
anything to do with whether marginal cost is the right way to quantify what
they "use".

Sorry, I don't see how I can state it any simpler.

Yes.

Because to do it any other way would require a group to pay for things they
do not use. Everyone should pay their own way. Don't you agree?

Ok, then we're at an impasse.

I don't think so. An impasse exists when no progress can be made. I think
progress could be made if you'd attempt to answer my questions.
