So now you want to tax those that give to the needy? Ouch. I would say you should shoot your dumb average Joes in government who are too dumb to go after the real transgressors. How could Americans hide income and wealth for decades without anyone in the US justice system realizing and taking action? It took a damn whistle blower to unearth this drama. The problem in your country is loop holes that exist everywhere and that nobody has an interest in fixing ( tax excempt contributions are certainly not one of them) and political contributions. Without the latter there would not be any lobby groups either. Fix the real evil instead of hurting those who are in the game to help and aide.
