Should of been mandatory from the get-go.....
Whens the last time the 'critters' passed a new law for citizens to *voluntarily* abide by ???
I'm pretty sure workplace verification was part of the Ronald Reagan 1986 amnesty but was never implemented so it would work in the real world with an SS# database. IOW employers can legally go through the charade of verifing phony work documents. There is no penalty for doing so.
I don't disagree, but I'll take my incrementalism and my silver linings where I can find them. With a voluntary period, employers have no one to blame but themselves if the program becomes mandatory and they're caught short of workers.
