I hate to be the one to mention this little known fact, but many average income people such as myself can not afford Leicas.
Sorry, I just don't agree with you, but I completely agree with Lee: it's a question of priorities. I have known people with well below average incomes who own Leicas and other expensive cameras. An anecdote I have told elsewhere illustrates an example.
Roger, you remind me of the fact that for the price I paid my laptop 3 years ago, I could have a used M3 body and a lens. Or a small Hasselblad kit. Or even a used Mamiya 7II.
I was into computers before being into photography, so I still ponder profoundly the expense of a 100$ Pentax lens to go on my Spotmatic, but I realize how quick I was to buy a good, solid laptop.
Funny how one's priorities change. The odd thing is that with the laptop I have, I don't feel I have to justify it as a "professional" tool. Computers are so common that this price is hardly something special. But buying a camera of the same price still means "going pro," and while that's a perception one may or may not choose to accept as valid, it's still a thought that the average consumer must confront.
We've been conditioned to accept a 1-2k$ computer as a normal household item, but for most people a camera is for snapshots at birthdays, so I suppose a Leica would look like a 600$ broomstick to them.
