I said neither of these things.
It’s not “give them work” as you implied it, it’s that the Europeans are highly unionized, and wrote laws barring them from work. Ergo, it’s a lack of labor freedom.
Daniel Hannan certainly was not saying America was better because we were giving people anything. Quite the opposite; he credits welfare for the lack of assimilation.
And he credits labor freedom; hire who you want, to the opposite.
