Jerry Kammer, in a column for the Center for Immigration Studies, writes the following, debunking the WaPo argument for open borders:
Jared Bernstein, who was an economic adviser to Vice President Biden before joining the Center for Budget and Policy Priorities, offered an assessment that threw cold water on the import-foreign-workers enthusiasts who write the Post's editorials. Wrote Bernstein:
One thing we learned in the 1990s was that a surefire way to reconnect the fortunes of working people at all skill levels, immigrant and native-born alike, to the growing economy is to let the job market tighten up. A tight job market pressures employers to boost wage offers to get and keep the workers they need. One equally surefire way to sort-circuit this useful dynamic is to turn on the immigrant spigot every time some group's wages go up. (p. 157)
This is basic economics - supply and demand - when you increase the supply, prices including those for labor drop. A ridiculously low wage may look good to someone accustomed to third world poverty.
The Biden loose borders policy increases labor supply, so wages will fall. Understand it as Biden’s payoff to his corporate dark money backers and the U.S. Chamber of Commerce.
