This problem is not just confined to GA. The whole country is being de-industrialized on a major scale with capabilities being exported wholesale or left to wither.
We are watching high-end precision machinery being exported at 10c in the dollar. Never mind the "advanced manufacturing" that is going to save us. Most of the skills and machinery required for that will be gone before the nation wakes up.
We will be competing for foreign aid in the future to make up for the lack of FDI because it's only our positive capital account that has allowed us our currently high, but declining standard of living.
Take a look at what the "mining boom" has done to our balance of trade and current account. It's barely a blip in a long and sorry trend into the abyss.
Is it any wonder the nation can't sustain expensive aviation infrastructure?
