There is a very direct relationship to consider here, because the consumers and the workers are often the same people. If one worker takes one week to manufacture an item which that worker is not willing to buy at a price of one week's wages, then they should not expect to be able to make a living from this.
What unions can do - and frequently have done - is raise the minimum price of goods and transfer some fraction of this to the manufacturing workers. If this makes the goods too expensive, then the factory closes down because people aren't buying them.
The cost of labour is substantially lower in various Asian countries. That isn't going to change, and you've effectively stated that you're unwilling to accept paying local labour similar rates. The conclusion you should be drawing from this is that the only way to make manufacturing work in this environment is to massively improve the productivity per unit of labour. You need to be getting away from people assembling things with their hands, and towards workers who build and maintain manufacturing automation.
Sadly, when this opportunity arose in the recent past, it was those same unions who tried very hard to block it, and were successful in that goal - manufacturing is still a laborious manual process.
