Turnbulls Tax and Spend Budget disaster, page-33

I've said it before and I'll say it again, our debt, US debt, probably the worlds debt
is simply beyond the realms of paying......Budgets in the not too distant future will
have an "allowance" for interest payments on debt incurred.......What's the US debt,
circa $20 Trillion, how are they gonna pay that back, indeed how much is $20T worth?
What would you do with $20T......I suggest not much.....What could you do with the interest
on $20T, more of the same and keep the wheels of the economy of the world drifting along..
