The cost of labor and resources outside the US is less,
therefore businesses source labor and resources outside the US,
which translates directly to a less equitable division of wealth for people who live in the US.
Why? Because these businesses are not owned equally by all.
If people want a more equitable distribution of wealth you can either,
'join the club' = start your own business and do the same (outsource resources and labor) or,
'put your money where your mouth is' = don't purchase goods or services produced/provided outside the US.
If you choose the second option the following website may be of interest to you:

The above website does not sell anything, but does provide an information database of products still made in the US.
It is amusing that Walmart the very epitome of this problem is expected to provide a suitable minimum wage when every aspect of their business defines the very problem causing the need of a suitable minimum wage. Forgive the run on sentence.
