Burning money is never sustainable. All you're actually saying is nobody can predict how long this particular bonfire will burn.

Whether sustainability is achieved by raising prices or hoping that costs can be brought down, you have to acknowledge that the status quo is unsustainable. If it were sustainable nether change would be necessary.
