The only consideration when it comes to salary should be for the employer to consider how much they're willing and able to pay for the average productivity of the next hire vs. that hire's contribution to the company's profitability. They already have the right to fire at any time thanks to lax employment laws; it's only right that pay reflects the profitability an employee brings to a company (rather than the average market rate for an employee). If that employee isn't profitable, then they can be fired. If they are, then they'll be paid commensurate with it. Everybody's happy.
