Too young to remember :). The above proverb was related more to the legal and creative accounting and other business practices which were later banned. I had in mind "Sometimes he made use of inside information in ways which would later be made illegal, but regulations were lighter in his era." - and dozen of similar sentences I found in various biographies.

>There's the trick, make cars illegal. The car manufacturers will be able to name their price and people will do anything to pay for one. They'll need to hide their factories but a little money in the right pockets should help.

- Sir, please empty your pockets. What do you have in that box? Are you sure you aren't trying to smuggle any automobiles?
