Try "we need to find a way to LEGALLY bring in 48.5 million immigrants into the workforce over the next 20-30 years."
One thing: taking care of old geezers (like I'm rapidly becoming) is manpower-intensive. The alternative is euthanasia, and that's wrong on so many levels.
Mark my words: Murder ("euthanasia") will be covered by Medicare in 10 years and endlessly encouraged by the democrat party media as the "right thing to do."
