How many countries have failed to pay back the IMF the money they owe, as I can't think of any?
As they tend to be the lender of last resort, the terms are never easy, that's why a country needs to face its own economic/debt problems earlier - as they have a few more options pre IMF.
The UK called out the IMF to financially bail us out in 1976, I don't remember their terms back then, but around that time we stopped throwing taxpayers money at inefficient nationalised industries, I suspect that there was a connection.
Greece pre crash, like many other EU countries including Ireland, took advantage of the very low Eurozone interest rates offered to them, as lenders saw some implied guarantee by the EU as a whole.
Greece's economy was too inefficient State top heavy, the private sector held back by red tape, and they were not collecting their taxes - so hardly a viable country economic model, never mind in any comparison to Germany.
Sure some of those problems have been addressed, but the election of a left-wing government and their views of how an economy should be run, was NEVER going to receive the confidence of their debtors to throw good money after bad, unless real reforms were made.
I believe the latest Greek plans were basically to tax businesses already struggling, while keeping most of the unaffordable State, which would have meant less revenues to pay the governments Fixed Costs - which IMO both explains why they were rejected and underlines their inability to make the right/tough decisions going forward - in or our of the EU.
