and constantly accuse us of having just waved our hands and made it all appear?
Because that is what capitalism is about. It's about rich countries staying rich, and abusing that position to get richer.
You see, it's simple: Germany has a lot of money (let's not discuss how they got it in the first place. They got it for free, from the US, who prints it for free). Germany lends money to Greece, and Greece uses that money to produce more money which is then - guess what - paid back to Germany with interest. Germany ends up having more money than before, and Greece ends up poorer than before.Why? Because Greece can't sustain an industry against Germany: even if they could, Germany wouldn't allow it: no country would lend you many for you to eventually compete with them.
This is broken capitalism, it's an exploitation of the system, and it leads to nowhere. It's just an elite of rich countries ruling smaller countries, and keeping them from developing, under pressure of different organisms like IMF, World Bank, Paris Club and others.
Is it fair that Germany has to give money away to Greece? Of course no.
Is it fair that Greece has to take loans to sustain their economy? Of course no.
Is it fair that the US can print money whenever it pleases? Of course no.
World's not fair. Let's not pretend Germans are saints. The worst offender is, of course, the US. Their debt is in the "trillions" and no one is talking about doing anything to them. They just raise the debt limit, and print more money. And it really doesn't make any sense: the US doesn't really have an industry or resources to back all that debt, and yet, they get away with it.
The truth is: poor countries just stay poor, and rich countries just stay rich. South-east asia has always been poor. They have a lot of industry now, and guess what? They're still poor.
There is no possibility for a change. It's been like this for over a century, and it will remain so. Lefties think "the US empire is about to fall" but this is far from the true. It's all fake money. It doesn't exist. China is the largest creditor for the US, and lefties think China can just demand their money back at any time. China can do this, and the US will simply default, China (along with the rest of the world) will crash, the US will throw boatloads of devaluated USD to China, call their debt 100% cancelled and credit agencies will rate the US as AAA+ again, cause they paid all their debt. The US will re-issue USD with new values and it will be back to normal. While everyone holding "old" USD will be left with monopoly money.
