You’re literally just describing an end to private property, where a privileged government representative can take anything you have. The “government job” will become so lucrative that the position would be passed down within families, father to son. It is already known how these economic systems function, I think.
I am describing a system where the government can take anything you have over a certain amount. (Or more precisely perhaps can take a proportion of what you have that asymptotically approaches 100% as your total wealth increases.) In my conception this money would then immediately be redistributed (as direct cash payments) to people with less. Government employees doing as you describe would also be subject to severe penalties. The purpose is to entirely eliminate massive wealth concentration.
As for why would anyone start a business? There's no disincentive to start a business in this scheme. I'd say the current system has greater obstacles to starting a business in many cases, due to high barriers to entry and regulatory capture by large players. The purpose of policies like the ones I describe is to encourage people to start small businesses and keep them small. You can grow your business up until its value is around that taxation threshold and then just kick back. We don't want people taking big businesses and making them bigger.
