Now the problem is that the IMF and some what the EU have demanded a lot of the Greeks and especially demanded certain things that is actually bad for the Greek people and country. For example the privatisation of public companies. The IMF wants this done now and as fast as possible. Problem is that the deals done are cheating the Greek people out of billions. Why should Greece sell public companies at 10 cents on the euro? Why not get as much as possible? That is one of the sticking points with the new Greek government. Then there is more cuts in pensions. At the moment you can barely live off a state pension in Greece, and they expect more cuts? Come on. Also none of the plans that the IMF and EU want for Greece include growth plans. Why is that? The budget has a primary surplus. It is time to grow the economy, but you cant do that by constantly cutting the public sector and adding new regulation/taxes.
Now on the flip side, I fully understand that Greece needs to keep going on with the reforms. I for one, would love to see a Scandinavia like tax system (not rates) put in place. That would do wonders for any country. This takes time and energy to implement, but once done the amount of fraud falls dramatically.
So at some point the EU has to give it self, while the Greeks have to do it as well. I suspect both sides are willing, but I also suspect that the main problem child is the IMF.
