Uh, how would you propose we legislate "job security?"
For starters, by either not allowing products made by Chinese slave labor or Latin American child labor into the country AT ALL, or, alternatively, by an equalization tarriff which cancels out the advantage of using labor practices that are illegal in America. Currently, slaves, children, and people paid bare subsistence produce products abroad which are allowed to be shipped by merchants directly into the USA to compete directly with products made by workers who are protected by laws against slavery and child labor.
Obviously the Americans cannot compete with practices like that, any more than a northern free labor cotton farmer was going to ever be able to compete with plantation slave-farmed cotton.
The answer is not to shrug our shoulders and say "Well, that's globalization". The answer iis to impose tarriffs that cancel out the advantages of child labor and slavery, so that the economic advantages to producers for using those methods is not allowed to create an undercutting market price in the USA.
These are not the same things as punitive tarriffs. The purpose is not to keep out foreign goods and protect domestic manufacturers. Rather, the purpose is to equalize the playing field so that countries with disgraceful human rights practices in their labor markets do not derive a competitive ADVANTAGE from those practices when they sell their goods in the US market.
As a practical matter, it means spending $5 for a pair of socks instead of $2.
Democrap Charlie Wrangle has the answer to that!
We just draft everybody at age 18, and keep them in the military until they are 70.
Problem solved.
Unionize!!
