"On 8 April 1933 the people of Western Australia voted to secede from the Commonwealth of Australia by a margin of more than two to one."
Don't act like it is only after the mining boom that WA has been pissed off about how they're treated by the Eastern states.
WA has already more than paid back it's debt from the early years of federation, so for how long must this child delay buying their own house while they pay for their parent's mortgage? (to use your analogy).
