This is how CBO Director Phill Swagel summarized it: "as a result of those changes in the labor force, we estimate that from 2023 to 2034, GDP will be greater by about $7 trillion and revenue will be greater by about $1 trillion than they would have been otherwise."
And there you have it: yes, the US hasn't added any jobs to native-born Americans in six years, as instead all jobs have gone to immigrants, mostly the illegal variety, but that's good news you see, because if it wasn't for these lovely creatures flooding into the US, wages would be higher (that's a bad thing according to the Fed), and the US economy would not grow by $9 trillion. Just please ignore that that $9 trillion in "growth" will come only thanks to $20 trillion in debt, almost all of it soaked up by these same illegals, and of course, a handful of corrupt, embezzling politicians.
