WTF G20???

According to their website, the G20 are the premier intergovernmental forum for international economic cooperation, representing around 85% of global GDP with a core mission of: 'Driving economic growth, unleashing innovation, and strengthening partnerships that benefit workers and businesses.'
As they are the premier economic bigwigs we really should listen to what they have to say. Countries like USA who have a national debt of £38.3 trillion or 120% of GDP. Hmm, maybe USA was not the best example so what about you China, debt of £18 trillion or 68% of GDP you say, okay, moving on quickly to Mexico. Debt at 61% of GDP or £11 trillion. Is it worth looking at you Japan, £10.3 trillion debt or 120% of GDP, so that's a no then.
United Kingdom, what about you? £4.1 trillion in debt which is 93% of GDP and India, have you managed to get yourself out of debt? Oh, £3 trillion or 85% GDP.  Canada, your sensible, is it worth...oh, £2.5trillion or 110% of GDP...sit back down.  
Now you are probably imagining if the 20 are so awful at running their own economies, what the bloody hell are they doing making the big economic decisions and you would have a fair point, it's a bit like asking Homer Simpson to run a MENSA club.  
Experts are saying that after America and Israel's disastrous war with Iran, another recession could be coming so you wouldn't take spiritual advice from an atheist or go to an arsonist for information on fire prevention but we allow our economies to be dictated by people with combined debts of tens of trillions.
So, as i understand it, we have leaders of the 20 leading economies who are all deep in debt, giving advice to other countries how to get out of debt.
Nope, can't see how that can possibly go wrong.
