Let’s presume for a moment your points are correct (IE: gov’t can regulate whom is hired when/where). And excuse me outright, I’m going to be all over the place I suspect.
Questions:
1) Does a Citizen need permission from gov’t to earn a living/work?
2) Does gov’t have the authority to determine what businesses are (in)valid for the Citizens? We see this Fascism (IE: biz licensee). Just look at the medallions for cab co. in NY and the like, liquor license fees, environmental impact studies, red tape, gov’t, regulations, etc.
3) How does the gov’t verify the validity of the possibly-to-be employee? SSN (a program that is Unconstitutional and already mission-creep’d leaps and bounds beyond its intended purpose)?? Passport? Drivers license (another gov’t encroachment on free travel, IMHO)? Utility bills?
4) By what authority does gov’t have to enforce whom is hired, but not what the min. wage will be? What ‘benefits’ will be offered? etc. etc. etc.?
Did I imply the employer is above the gov’t? No, I did not. What I did state is that it is NOT up to the employer to validate the Fed. gov’t is (not) doing its job.
Is not employment a contract? “Here is what I am willing to offer for services (work) rendered”? A1S10 specifically states contracts are to be enforced (yes, only when entered into by willing participants, yada yada). Nowhere is the Fed granted this authority either.
If the employee is found to be illegal, the Fed has the authority to remove that person from our borders.
As to your ‘vested interest’...When the Fed. gov’t BEGINS to do the basics of its authorized functions (IE: borders, protecting Citizens Rights), you might have a point. As to the ‘Balkinization, the States are where the experiments in Laws and Liberty are to be ‘fought’; in your postulation, if one State became the shining example, the gov’t could step in to stop people from confirming with their feet (moving). No. You give the gov’t too much authority it never had; it is only to PROMOTE the general welfare....not try provide.
The Individual comes first and foremost as they are the ONLY entity with Rights.
