Pot, kettle.
How is asking a question "wrong"?
Actually, absolute dollar amounts are meaningless. Now, if you had used inflation adjusted dollars instead of GDP, that still wouldn't be a good measure, but at least it wouldn't be completely silly.
How is it silly? Because (acording to you), it's been mentioned for less than twenty years?
That statement is neither well formed nor shown to be relevant. If you think that foreign borrowing is what's truly important, why not measure foreign borrowing as a percentage of GDP? Nothing you've said has given any reason why GDP is, if not perfect, at least better than absolute dollar amounts.
