To be clear, I don’t have a problem paying taxes in Germany. The problem for me is primarily how hard it is to set up a company and deal with bureaucracy here. And even though there are great alternatives like Estonia, they sadly don’t really solve the problem.
In contrast, and I don’t know the US but how many people live in Delaware? :)
Then you have to choose between entrepreneurship and family. Germany is the country to have a family and work for a company your whole life, not for business ventures.
Then don't have the center of operations in Germany when there are lower-tax EU countries.
