Conservatives say they are for free markets and free enterprise, but then I read stuff like this (have have added the bold):
Lynch supports Obama’s unconstitutional amnesty, believes illegal immigrants should have the same rights to employment as American citizens, opposes voter ID laws, advocates federal intrusion in local law enforcement under the guise of civil rights, supports the government taking private property on flimsy grounds, and offers no opposition to using drones against American citizens.
I agree with some of these concerns, but the one in bold is a real head scratcher. What theory of free markets do Conservatives hold that accepts as valid the government licensing of labor? On what possible grounds should a government bar me from hiring, say, a Russian immigrant to do my programming? Or crazier still, why can I hire a Mexican in my Mexico office but can't have the same person working for me in my Phoenix office?
I have a theory about the Romans that is probably shared by nobody. The Romans were strong and powerful and vital when they were creating a variety of citizenship types to accommodate multiple peoples who entered the empire in multiple ways. In particular I think of civitas sine suffragio or citizenship without the vote. But this was just one of many variations. By the first century AD (or CE per the modern academic trend), a lot of people of a lot of cultures and races and over a wide geography called themselves Romans.
By the end of the empire, the "reforms" of Diocletian and Constatine purged all flexibility from both governance and the economy (in sum, their laws amounted to the Directive 10-289 of the ancient world). By the time the Empire started falling apart, they had lost all ability to integrate new peoples or innovate with citizenship models. What was eventually called the Barbarian invasions began decades earlier as the attempted barbarian migrations. The barbarians wanted to just settle peacefully. And Rome desperately needed them -- their system was falling apart as their farms and countryside was depopulated from a combination of government policy and demographic collapses (e.g. plagues). Rome desperately needed new people to settle their farms and form the new backbone of the army and the barbarians desperately wanted to settle and had a lot of military skill, but they couldn't make it work.
