Very different clientele though.
The spamcan market, as in going from A to B, has been dead on its feet for years. It's been kept standing up by U.S. consumer inertia, patriotism (not saying that's a bad thing), and ultra conservative attitudes in the GA market, especially in the USA where you could stick a pair of wings onto a Zanussi washing machine and quite a lot of GA pilots would think it looks really good. In fact it is quite possible that "Flying" Magazine would do a perfectly straight faced review of it, so long as it flew well.
Cessna have been kept in business by there being little else for the circuit bashing market, and by numerous short field / utility applications.
Piper are dead. They are kept going by spares production for the huge PA28 fleet.
