To make it short and easy to understand: Your country does NOTHING in order to enable you to get these medals or fight for a CO.
Work Tax: The country provides you recources and you pay Taxes so the country can finance a military to fight for or to defend recources. A fair deal.
VAT/Import Tax: The country has a Market and you pay Taxes to use it. Alternatively you can pay taxes to another country to use its market. Fair deal.
Now the CC Medals and CO....
True Patriot Medal: You fight for your country, get rewarded by the game and now your country takes money from you because you helped it/fought for it, really?
You have to pay taxes to your country to fight for your country!?
FF/Mercenary Medal: You fight for random battles for random countries and against random countries. Use weapons, food nand get rewarded by the game. Now your country grabs into your pocket and takes taxes for it!? The country did nothing to make it possible to fight in battles, but wants to take taxes?
CO: Same principle. You fight for a Random MU/Country, your country mosly has nothing to do with it, but takes taxes. WTF?
