Don't forget there are a couple hundred countries besides US. I make a relatively decent living by our standards, but nowhere near close to $100k/year. $150-250 per year is quite a bit of money for us.
It should be possible for a small devtools company to price differently based on locale, but I expect the support costs would then dominate any of the lower prices customers.
I think the core point missed in this thread is: developers write software for a living. They do not want to pay for something they would love someone to pay them to write.
You see this in other professions. A car mechanic doesn't want to take there car to someone else. A doctor tries to avoid general checkups with other doctors. A realitor will sell their own house. A grass cutter doesn't hire someone to cut his lawn. The person who makes lawnmowers doesn't buy one he makes one even if it takes longer.
I would love for someone to pay me to write an IDE. I've been in that situation a couple of times in the past (SQLWindows, Visual Basic) and it was a lot of fun.
However, my current job is developing a voice response system for restaurant drive-thrus. I don't have time to write my own IDE right now!
So I farm that out to JetBrains and get to use all of their awesome work for less than fifty cents a day.
If that's too much, their free versions are very good too.
I may also take exception to this:
> A doctor tries to avoid general checkups with other doctors.
Wouldn't the opposite be true? As far as I know, every psychiatrist has a psychiatrist, every counselor has a counselor (or should), and I would guess that every doctor has a doctor.
A doctor is more likely than the rest of us to have particular insight into their own health, but I don't think they try to do it all alone.
Of course I'm only speaking for myself. If anyone prefers to write all their own tools, more power to them!
> Then there is this saying that if a lawyer represents himself in a court, he has a fool for a customer
Also making the reverse assertion true too: that client has a fool for a lawyer :-)
Of course, many unsuspecting non-lawyer clients also have fools for lawyers; it's hard to tell whether or not your lawyer is any good (unless his name is Saul Goodman)
