The economic indicator is the purchasing power of the monetary unit. If you've traveled before you'd know the purchasing power of your money varies from country to country. Invalid argument...
The main issue here is people believe that everything in the market will get cut to 10% current value. Many other disagree and that is what will create the disparity in the purchasing power of our monetary unit (gil) from current to ARR economies.
Many claim the markets will all fall by 90%, many others including myself don't. This is the common fallacy when in real life, any political system tries to take over and control an economy. You can crunch the numbers all you want, but people acting in any environment will always remain somewhat unpredictable.
