Generating wealth from employees, has nothing to do with generating wealth from customer data.

If what is of value is customer data, customers can and should own and control the entity generating the monetary value from their own data.

Employees at least get paid, knowledge workers sign over their intellectual property in exchange for a salary. There is no concept of data ownership, but there could be something similar. Imagine companies having to license your data and pay you a stipend or the like.
