I agree with your first point. Why is this happening though? We had to get more and more money to start paying off our debts on our own.

This isn't happening yet although the past goverments(greek and europpean) where pretty confident the past programs would have worked. Will it ever happen? Continuing with the same recipe, the answer is unclear. Ironically, no matter how catastrophic a grexit would be. The consequenses for the Greek people are way more predictable, just because you can expect the worst. From talks I've had with the Greek people the past years, everyone was having a tough time, but we all agreed on the fact that staying in the eurozone was for the best.

After recent events, they have started to feel more and more discouraged. The "reforms" that had to be implemented where targeted at their life, which was already hard. And you shouldn't have a doubt. Greece took the reforms, the troika asked for. Every few months, in order to get money, the troika evaluated the progress and asked for reforms to be implemented, or no money. So the "Greece is still doing bad because she didn't implement any reforms" argument is invalid. Contrary to what the media tells you about Greeks(lazy fucks, living off your money, etc) the majority of the Greek people know how to work hard and have themselves been through tough times in the past.

The whole thing is turning fast in a matter of EU-scepticism, and the Greek people have starting to feel more and more like sacrificing themselves for matters going beyond money. I don't expect you to understand, but you can't miss money when you're already missing them.

The debt is clearly unsustainable, the reforms asked from the Greeks are once more the same kind of poison that didn't work in the past(and the institutions have admitted to be wrong on some occasions). Greek people have started to feel there is no will from the eu to make Greece a country which can pay off it's debt, just a country indefinitely in debt and under programs that are actually protecting those with power. It's rapidly turning into "a peasant who is a master of himself" or a "peasant with another master. And Greece has a history showing clear allergic reaction to any form of occupation or slavery.
