The main thing preventing significant price increases as you suggest is the threat of competition. Canadair and Embraer have more than enough expertise making good sized regional size planes to jump into the larger plane market if the prices go high enough to justify the development costs. Gulfstream, Bombardier, and Dassault are even more players who could cut in on the action for the right price increase.
A large part of the problem is likely consumers just not knowing about it and the carriers not enabling the chips to drive business to their subscription services. A proper efficient market requires accurate information on both sides of the transaction.
Back when I had a Note 2 I hadn't even know it had come with an FM chip in it. After I found out I called Verizon to complain it wasn't enabled and their support in turn didn't even know anything except to tell me I need more data plan if I wanted to stream radio.
I don't even list my employer on my FB profile.
My vocation is listed as "Professional Crash Test Dummy"
My employer is listed as "I work at an office"
I don't even list my location or educational institutions. FB occasionally nags me to update my profile but I ignore them. The less FB knows about me, the better.
