So you want a flat tax...
Name a reasonable size country who have implemented it...
You can say Hungry (or Romania)... Hungry is the largest recipient of EU aid per capita...
So the RW here want to put in a tax system like Bulgaria (10%), Romania (10%), Hungary (15%), Kazakhstan (10%), Uzbekistan (12%), Estonia (22%), Georgia (20%) and Bolivia....
I will not all these countries also have VAT at 20%+...
This is why no one has put it in compared to a progressive tax scheme... The system is for loosers...
