Joe Biden's First Day agenda includes a proposal for comprehensive immigration reform. Just as Dems divide over the Green New Deal and Medicare For All but unite in loathing Trump, the fractured Republican Party will come together to derail the latest run at immigration reform.
In a nightmare scenario the moderate Dems in the Senate (Sinema, Manchin) are so committed to giving Biden this win that they vote to change the Senate rules and eliminate the filibuster. More likely, immigration again goes nowhere.
Biden's website on immigration is here; he links to a 2013 CBO study assessing that attempt at reform. Their summary: more workers leads to a larger economy, but smaller on a Per Capita basis; until skills and jobs alignn, unemployment rises (a bit) and wages fall (a bit). The return on capital rises, however, since it is slightly scarcer relative to labor.
So for Chamber of Commerce Republicans its all winning - more customers, cheaper workers, higher return on capital.
For Democrats, more unskilled workers plus the Biden Fantasy Minimum Wage of $15 should boost unemployment but (more importantly!) boost the need for the sort of compassionate safety net Democrats live to provide. More winning!
And yes, I'm already getting sick of all the winning.
