Just as I suspected. Move out of higher priced city, expect a pay cut. Even if this particular company is throwing in one time moving costs. They'll recoup that in 2 years time on the lower salary and they have you by the balls on comp once you relocate to Idaho or somewhere similar.
Stripe is paying employees $20,000 if they relocate from expensive cities such as San Francisco, Seattle and New York, where the company has offices. But workers who make the move will have to take a 10% pay cut.
