In 2012 I had 100,000 Euros income paid 86,000 Euros spent on taxes
In 2007 I sold my business to a major government contractor, that is pretty much all they do - government contracts from food service to defense, for an eight-figure sum. My taxes were nowhere near your taxation rate and now they are even less, I pay less in capital gains taxes than I paid before. (I can afford an accountant and a lawyer now.) The only taxes that I pay "dearly" on are property taxes and I do get raped there. I really can not complain - I still pay less than I probably should.
For those who would say that I should pay more... I pay exactly what is due and avoid any taxes possible. I donate as much as is reasonable instead. I consider it my same social spending only I get to spend it on feeding hungry people instead of bombing brown people.
But, come on now... You spent an absurd amount on taxes, overall taxes, and that is not cool. Now if you were making a huge some of money, say 10,000,000 per year as some jackass CEO, then sure - the amount is still absurd but the overall amount that you'd keep is still acceptable. In your case? I do not blame you for being unhappy. That is simply unacceptable. The obvious result is that you, and others like you, will go elsewhere and the business will move elsewhere when and where it can unless they provide some very compelling reasons to stay. At those rates? I am going to need a daily supply of hookers and blow (and blackjack) on the government dime. Otherwise? I am taking my ball and I am going home. Fuck you and fuck your society (no, not you personally but the society you left) because I do not like my neighbor that much. Oh, I love my neighbor, so to speak, I just do not love him that much.
You kept 14% of your income... I am shocked that you stayed as long as you did. You probably would have been better off being on welfare. It probably pays better. Note: I have no idea how Greece's welfare system works. I have been to Greece twice (I once stayed for six months while I did some work there) and never asked about the welfare system but I did deal with their government and, if that is any indication, you may well have been better off on welfare. (The myriad government agents that I consulted with were almost always different people, almost always had no idea what was going on, and were really difficult to contact.)
Seriously... How did you manage to put up with that for as long as you did? Is it the only job you could get? Was there a compelling reason to do so such as a significant other? I'd need hookers, blow, and blackjack and I am not going to let them skimp on any of them.
