It's not speculation, it's economics. If you have to pay a higher wage the number of available jobs decrease. It's supply and demand. There's not an infinite amount of money in a company's budget.

It's also not a company's job to incentivize where it's employees live.

I understand where you're coming from but there's nothing inherently wrong with paying different wages for the same work if it's a consensual agreement. If one worker is satisfied with his salary, and is being paid well for his area, the only reason to complain about a worker in a costlier area being paid more is envy/jealousy.
