The market wages for most of these types of jobs are above the minimum wage, making your argument irrelevent.
The reason that labor is more expensive in the U.S. is because we have such a higher living standard. If you want to live in a mud house and drink sewage so you could have cheaper clothes then move to a third-world country.
I think you missed something.
When I was a kid, almost all our clothes were made here, we had a wonderful standard of living for ANYONE who was willing to work, and the country was not a cesspool. Now, just how was that possible? Let's have a short (I promise) overview.
Instead of having in attitude of
entitlement, most upstanding people had a desire to express their work ethic, starting at a rate that the market would bear and then moving up from there. Folks taught their kids that they had better do well in school or they could end up like that "bum" over there. The order of the day was
personal responsibility. We were a country of
rugged individuals who struggled together as a solid community, unafraid to place a nativity scene in front of the Library.
All of that has changed. The admonitions of JFK and MLK have been lost. Now we have far more intense regulations, a nanny state, and have a population that used to work hard to get ahead that now demands special treatment, workplace sensitivity training, and "personal days".
If you wonder why we don't make our clothes, compare those who stitched T shirts for piece work pay in Pennsylvania in 1973 to a person of similar age today. The one who worked was clean, courteous, and showed up on time. Their counterpart is louder, less educated, more obnoxious, and demands "equality", yet is unwilling to earn their status.
Our production has largely moved to places where people are happy to have a day's work, and away from where government has dictated the environment for labor.
