Changes to the legal immigration system are an entirely different discussion, as I see it. If we got rid of chain immigration, we could conceivably increase the absolute numbers from India and China, which are the most populous countries. The legal immigration system needs tweaking, but it is not “broken.”
I hate the words “broken” and “fix” in regard to these problems. Too often they conflate immigration and illegal entry in the listener’s mind, if not intentionally in the first place. And they imply that something terrible has happened and so requires immediate action. The only thing broken is the fence.
The broken immigration argument drive me crazy. It is a play on words, it is like saying a perfectly good engine is broken if it is not running. I guess technically it is broken in some sense of the word but just start the dang thing!
