If your attitude is common in Greece, then I guess I can see why you are in such a mess.
This is a matter of investment. The 80.000 euros was an investment to get something done which, if done quickly, could pay itself back many-fold. You have to look at the future rather than looking at right now. Reducing debt may not seem like the same thing as making money, but it really is.
Can you say you will not spend 80 euros for gasoline to go to a last-minute job interview that is likely to result in a much better job? You could just save money and walk, but once you get there it might be too late.
I have many Greek friends in the U.S. who do not have the same type of attitude and are very hard workers and are willing to invest time and money, even when these things are scarce, for a chance at improving their situation. I do, however see and respect the strong family values that Greeks and Greek-Americans share.
I agree that you shouldn't throw money around like its nothing, and 80.000 euros is not nothing. But sometimes you have to bite the bullet and act quick and trust the best information you have before you.
I also agree that corruption in gov't and society can be very disheartening, especially for someone who is doing their fair share to help get the economy on its feet. In fact there is plenty of corruption here in the U.S. as well, and I wouldn't be surprised if we spend our way into insurmountable debt in the next couple decades also.
