No, it's not supply/demand economics, that was my point. It would be if Americans created jobs that immigrants later filled. That is not happening.

Rather, both Americans and immigrants worked hard to build a tech industry that then created jobs. Without the immigrants, the Americans would not have been able to create an industry more significant than, say, the Japanese or Italian tech industry. Thus many jobs would not exist, and the wages would not be higher.

You did not say words like "create", "stolen", "give", and "take", but they are implicit in making your supply/demand argument work.
