“What is the robbing of a bank compared to the founding of a bank?”* ― Bertolt Brecht
*Sometimes you also see this translated as “Robbing a bank is for amateurs. True professionals found one.” Language-freaks might prefer this version due to the dual meaning of “found”…past tense of “to find”, which suggests you don’t have to make a bank when you could just take one for yourself. Remember: rob a bank, and you might kill someone, found a bank and you could make a killing.
