Aviation is too expensive

What's wrong with general aviation?

An old crapper Piper from 1978 costs over $50,000. A nice one cost $180,000.
These are relic machines with instrument panel lights and loose door handles
worse than any yugo ever had. I'd say an old Cherokee from 1978 should be
worth about as much as a V.W. from the same time period: $2500. Especially
considering the absurd yearly expenses required to keep one legal. If a v.w.
bug had to have an annual inspection that costs what a GA aircraft
inspection does, nobody would pay a cent for one.

A hiker's GPS runs $199 while an aviation version costs $1,999.

Why does an aviation spark plug cost over $20??? It's just a plug! It should
cost $1.99 for a good one! A far more complex product with dozens of
precision parts - a digital watch - can go for as little as $5.99 at
Walmart.

Why does the 36" fiberglass pan of a Warrior (the chin part where the carb
intake is on the nose) cost 5,000 freaking dollars???? It is only glass and
glue, after all. There is no structural support or anything like that
involved.

Fuel is $2.65 for self serve 100LL! Does it have pure gold flakes in it? Why
isnt it $1.50?

Maybe modern pilots are just money bags who dont care about costs.
