This is usually their excuse, in point of fact.

I don't doubt the first year or two they'd sell several thousand a
year-but after the first thirty thousand the demand would peter out
worldwide. The number of active pilots wouldn't drastically expand.
They would be on the other side of the production curve in a few years.

The former WarPac nations make some nifty small airplanes they can
never seem to market here-apparently in Europe they are standard
category aircraft-and the demand is short of the supply even there.

There is a demand but it's small.
