The change in salary is not in proportion to the change in an employees cost of living.
FB (and other companies, in all fairness) is saying "If the COL is half that of SF, your salary will be cut in half". Whereas the employee is looking at "I only spend 50% of my salary on living, the rest goes to paying off loans and investments", which results in a net loss in their after-COL loan payments and investment opportunities.
