Too much at stake. The Bitcoin power brokers will do something when there income and wealth begins to deteriorate.
Yes they will just sell all their coins and watch the suckers suffer. It's just easier to ripoff people with 100$ transaction fees until it works, and then when the castle of card collapses they just sell their coins.
It's definitely easier to just sell your Bitcoin and move on to another currency, and do the same thing there, than to just fix things in Bitcoin.
