I guess it depends on the cost of shipping in terms of money and time and any other costs associated with buying from another continent.

Global labor costs are rising, rather than decreasing. China has seen substantial increases in their labor costs over the last decade. That works against them and in favor of robotics (which will perpetually fall in cost).

Generally speaking, people always want to be paid more, but people have a very finite output capacity when it comes to base manual labor.

Robotic productivity has a radically higher output capability over time.
