Ya in all of the world free thinkers who are smart, let alone come up with ideas that work.. they are hated by the masses of normies and foids, who want them stopped, silenced, dead, or at least banished from their lands.
People like feudal hereditary elite who live in castles, the masses of normies don't mind, because they can say 'hey its just luck if I was born into that noble family I would live in the castle. Mafia or gangsters the normies don't mind either, because they can say well they just stole the money.
But what makes normies go berserk and use state power to shut down is somebody who was born like them and went to the same school, and now he lives in a castle because he was a great businessman or engineer or something with his own initiative.
The easiest way for normies to shut down an inventor is just to call him a liar and say it would never work. And outlaw his invention in their country. Then the normies can laugh at him and call him a moron for thinking that would work, or better yet just ignore him. If he tries to explain to the normies why it works, they just talk over him and call him a moron and won't listen.
