Ahm, no. That's absolutely not true. As a prominent example of German Help, here is the history of the Siemens scandal[1][3]. Also, German's choice for PM when Papandreou quit, was Loukas Papademos. It's the guy who in 2001 acted as a bridge between Goldman Sachs and Greece to false statistics and allow Greece into the EUR. Isn't a kind of strange choice? There are many more situations (military equipment, MAN, etc.) where the German government actively undermined Greece.
Germany, unfortunately, is seen as the arch-enemy along with Brussels in Greece. After 6 years of austerity measures and governments who followed policies dictated by the troika (ECB, IMF, EU but mainly it's Germany) we rank #1 in Europe in suicides, the economy is worse then ever and the public debt has gone up instead of down. At this point many Greeks don't care what a Grexit would bring because they already trespassed the point X of "caring". They are already poor by all means.
That said, it's true again that Germany flushed billions of EU in saving the Greek economy. But almost all of that money was used to keep foreign banks happy by paying high yield Greek bonds owned by German and French banks mainly. The rest of the money was flushed to Greek banks owned by heavily corrupted bankers (e.g. Latsis - Eurobank). Even in situations of small banks like ProtonBank[2] were kept because declared of "national interest" (Ev. Venizelou - Leader of PASOK former Finance Minister and Vice-President) and thus bailed-out in the sound of millions while some pensions went as down as 350 EUR/month at the same time.
So to make a long story half-long: The German government is an extreme supporter of the old, highly corrupt, heavily bribed (by many german corporations) Greek government which doesn't make sense. Merkel is crying home for the Greman tax-payer when indirectly the only thing she really did was just handing money indirectly from the German taxpayer to the German banks via Greece (with huge interests). Truth is that given the results, Germans were more than happy to vote Merkel, so in a strictly political her policy was extremely successful. The only problem is that now all over Europe there is a strong anti-German feeling: Italy (M5S), Spain (Podemos), UKIP (Farage), France (LePen). So give it another ~ 2 years and Greece will be the least of Germany's problem.
Now the real problem Germany and EU is facing is this: If they bailout Greece, they must bail-out Italy and Spain too. Maybe France will follow. But the Greek debt is small so it can be done, if there's political will and a sort of promise that Greeks won't fuck up their economy again anytime soon! But for Italy it's a different matter, if Italy and Spain require a cut oh well... I'm not sure it's even possible mathematically speaking. On the other hand mathematics was never a part of economics, it's mostly politics. There are logistical ways (e.g. the EU buys bonds from failed states and hides them in a locker room for eternity at a very low rate which the countries could start paying God-knows-when...) to bypass this, but the problems are at the level of politics mostly. If Merkel concedes now, the opposition inside Germany will literally trash her and she will not be able to come up with answers, since the story of the poor Greek who spends more than he could afford is the one she choose a couple of years ago.
Sorry the long answer! Jesus I didn't realise I produced so many chars :-P
