Go to Romania and open a "microintreprindere" , you will pay only 1% up to 500 000 euro, of all money that comes in. And you can 3 in your name, and those 3 can also have 3 more, so it will always be 1%. You need to hire yourself, but you also need health security and a pension., so it will work in your favor. Diviedents it's 5%, so total will be 6%,but you can keep it at 1%, if you for example earn 70700 and buy a 70 000 TESLA CAR.
If you can care to limit the 5% , you need to︀ find a country that excepts dividents from taxations, like NHR portugual if i am not︁ wrong. but it's not worth it. 5000$ for 100 000 , airplane tickets are more︂ expensive.
He can pay 1% taxes in Romania and also hire himself here.
Nobody will know how much time he stayed or not stayed in Romania,︍ because it's in EU as Germany is. He is not aware Romania is 1000% times︎ safer than his homeland 🙂
