Profiting from what?
You can't be serious Holly...
Corrupt government officials at all levels have been known to receive kick backs from those making the big profits, in this case those who've decided to move their manufacturing to countries like Communist China of all places for those 1930s labor wages.
It goes something like this Holly:
""Listen Mr. Chintoofat, my buddies are going to pass laws outlawing the use of incandescent light bulbs in the U.S. and I know a manufacturer who can design the new government authorized light bulbs. He can develop the process and machines that make them. I will put you in touch with him and I'll make sure he's fast tracked to move his company to your country and your part of the deal is you supply that dirt cheap peasant labor.
