why the us is doomed but oz is not

When I put the US Debt Clock on my Home Page
(http://www.radiograham.info/debt) the US Debt
to GDP ratio was 97.68% and steadily rising.

Today it was 98.42% and it was steadily rising.

And while-ever the US Government's revenues
are $600 (for every $1000 it spends) that ratio
cannot help but rise, until the US is bankrupt.

The Fed can't drop interest rates below 0%.
So to supply the missing revenue it will have
to print or borrow more and more money
to keep forestalling Federal Bankruptcy.

Two Airports (one in Dallas and one in Perth)
explain why the US is doomed while OZ not.

I didn't take any pictures of what I saw in Dallas
last year lest Homeland Security pounced on me.

But there was a Special Departure Area
from US troops (in full battle gear) and
a Special Tarmac Area for huge jets
that transported men and supplies
all the way to Irag and Afghanistan.
There was a war memorabilia shop.
The same evidence (of massive
military spending) could be
seen at other major airports
that I visited in July 2010.

BY WAY OF CONTRAST:
When I landed in Perth just before Easter this year
I went to the Taxi Area and the queue was huge.
But the taxis kept coming and coming and the
huge queue kept moving, though more jets
were landing and adding to the queue.

The fascinating part was no men in battle gear
could be seen BUT hundreds on men in orange
Mining Gear (on Fly-In-Fly-Out contracts) were
in the Taxi Queue - my guess about 15% of
the incoming and outgoing passengers.
Mining jets had a departure lounge
like US military jets did in Dallas.

America SPENDS Mega-Bucks on Two Wars
and is heading for Federal Bankruptcy.

Australia EARNS Mega-Bucks from Mining
and is heading for a Budget Surplus.

So guess where I'm investing my money.
