This works because people these days have no clue, they provide their ideas everyday to companies without any thought to what it is worth. On top of that companies for years and this goes back to the 90's make people sign agreements that state they do not own ideas they develop while working for a company, it is all the property of they company. Some company still pay for ideas and cost savings and the such, but most are not paying out anymore.
If you really have a good idea and you know it will make money, never share it at work. work on it at home and quit the company can do it yourself.
