"Could you explain to me the fallacy of that argument? "

You are equating participation in the world economy with open boarders.
That is simply not correct.

"I then said, "And all three of those countries have a very healthy and large immigrant population." That isn't an argument. It is a statement"

Those countries have LEGAL immigrants, who they chose themselves, and didn't have walk in through the bush into their countries.
And most of those legal immigrants are very highly educated, very highly skilled individuals.
Heck America is a country of immigrants, but its got to be LEGAL immigrants, and WE have to chose who comes into our country, not the Mexican movement.
How hard is that to understand?

"You are equating participation in the world economy with open boarders."

Not only am I not doing that, I haven't even mentioned "open boarders". Or even "open borders". Which, by the way, we don't have.

"And most of those legal immigrants are very highly educated, very highly skilled individuals."

You are just making stuff up aren't you? Most of those legal immigrants are house cleaners and nannies. End of story.
