Why do all the controllers of western societies wear dark suits like uniforms? Why do all their trainee controllers aspire to dark suits?
None of them want to be anonymous but all of them want to look the same, dress the same - apart from the cost of their cloth which has to be seen to be expensive when looked at up close?
.... and then, after their careers are over, or when they become famous, they wear ordinary clothes like the normal person in the street.... it is even the sign of the power player in a group of true players - the richest and most powerful often wears trendy casuals...
But the richest players\controllers always wear dark suits
Why is that?
