I'm not seeing how this matters, they were already doing that - the market is a big auction to work out the overlap between lowest salary employees will work for and the highest salary employers will offer. In that process employees also use data to figure out the highest salary that will be offered. The thing forcing employers to pay the salary they do is that if they offer less someone else will gazump them for the employee's time. It has nothing to do with the circumstances of the employees lifestyle. The lifestyle adjusts to the salary.
This allows all sorts of normally illegal discrimination via ai pass through. Never hire pregnant women, sick people or employees over 30 again. Target for race and religion whatever you want. Basically everything that’s scary about chinas social credit score except private run with zero accountability.
