We have an historical precedent to draw on in The U.S., fortunately. Slavery was a component of Southern aristocratic feudalism, which was just outsourcing to wage free labor. Ironically, though, with all that wage free labor, the South was ill prepared for the Civil War. They had less than 10,000 factories, to the Union's 100,000. Why?
Alexander Hamilton's tariffs on cheaper imports from Britain provided the impetus and resources for the U.S. to build up the infrastructure required to make its own weapons, etc.
The Confederacy, however, invested little in labor or infrastructure, so, once their ports were blockaded, they were doomed.

What we have, today, is brutally efficient, nonprofit, government owned infrastructure development and protectionism in Communist China, even more comprehensive than Lincoln had,

and "free trade" Confederate style outsourcing to cheap labor economic policy in The Anglo countries, with a lot of treasonous exchange of technology. The consequences are more dire now, however, as it's become obvious that an Orwellian, organ harvesting, communist dictatorship has just about won The Cold War over democracy and free speech.
