As cited above, the GDP per capita in Germany doubles every few years.
How many times more do you think it has to be doubled until you and your friends deem themselves wealthy.
They never will. Because you, too, define wealth as being able to look down on others (in your social environment).
A large part of the world’s population would consider themselves extremely wealthy if they had even near the income of a German worker earning minimum wage.
On a global scale, German minimum wage workers are very, very wealthy.
The only reason you’d ever consider German minimum wage to be too little is if you’re used to extreme excess, if you’ve lived in a hyper wealthy environment all your life.
You’re so used to extreme wealth, that you deem slightly less extreme wealth to be poverty. You consider it to be poverty, because the people surrounding you are even wealthier. You consider it poverty, because you can not look down on them.
