Ireland's total real economic debt runs at a staggering 524% of our GDP and 650% of our GNP. At 4.5% per annum cost of funding overall debt, the Irish economy interest-rate bill on the above levels of real economic indebtedness runs at circa 29.2% of our GNP. Do the comparison here - Ireland's interest-rate bill is equivalent to the total annual output of the Irish Industry (that's right - all of Ireland's Industrial output in 2011 amounted to less than 29.3% of our GNP). This is deemed to be 'long-term sustainable'... right... Ireland's real economic debt is 14.4% ahead of that of Japan!
