“Margarine was outlawed for decades.”
Yeah, I remember as a kid right after WWII we had margarine that came white in a bag with a capsule of yellow coloring that you had to break and kneed into the white mass. This was how the margarine producers initially got around the butter lobby and their anti-competitative laws.
Here in CA they have been using Kevlar reinforcement in asphalt overlay jobs for years.
Due to union electricians, San Francisco still will not allow Romex wiring. It has to be conduit or BX, and for years paint rollers were illegal in SF thanks to the union painters.
NYC still bans Romex, but half the drivers are unlicensed illegal aliens.
