You're by definition a leech when instead of being allowed to go bankrupt you're feeding on other people's money (so called "Government support").

That's not how banking got started back in the 15th-16th century, I never read of the Genoa bankers for example asking Philip II "hey, why don't you let us rob you of your South America gold?", as far as I know it was the other way round (Philip II screwing the Genoese bankers). But then again, back in the day we didn't have main-stream media Keynes-ian supporters saying things like "if we dont' give our money to support the banks the whole system would come crumbling down".
