What really kills me about this idea, is that the children of rich people have no drive or reason to try to accomplish anything. They're born into the lap of luxury and want for nothing, they could just sit back and let their needs and wants be catered to... but yet they don't, they go out and start businesses and create music and write books, because the drive to be productive and useful is innate.
No healthy person who could live comfortably on welfare would be content to just sit on their couch all day, they would just be driven to finding their own ways to contribute.
This seems like it would be so easy to game, the way it's written the "owner" of the business gets the right to vote, and the business has to have a physical presence in the town.
It would be trivial to buy a small building in town and have it jointly owned by multiple LLCs, or lease portions of the building to multiple LLCs to manufacture votes.
The intent of the law isn't even necessarily bad. If you have a small business in the town but you live just outside it, it does seem like you should still have some say in town politics. But there's little chance that this won't be systematically abused.
