This is neoliberalism. Speaker Pelosi wants open borders. Joe Biden made a similar argument in 2015 (see Joe Biden and the Ultimate Source of Our Strength: “an unrelenting stream of immigration, nonstop, nonstop”). Progressive Democrats stand with the corporate state when they argue for open borders. (See The Immigration Situation; The Impact of Immigration on Labor and a Nagging Question.)

Pelosi is lying or repeating what she’s been told. There is no labor shortage. Real unemployment at the very least approaches eight percent of the work-force. It’s greater than that when considering the redundant population managed by the custodial state—not just the prison system, but the ghettos, too.
A smaller work force drives wages higher—and that’s why Democrats and the corporate elite seek open borders and desire to keep immigrant labor in the southern and western states. It’s also why they portray southern rural and urban working class families as “racist,” “reactionary,” and other nasty things. They delegitimize their concerns while conditioning the masses to lose empathy for them.
Corporations use open borders to draw super-exploitable labor to the United States in order to inflate the industrial reserve army of labor and push down wages for native workers. Half a trillion dollars is annually transferred from the US working class to the capitalist class via the super-exploitation of migrant labor—many more hundreds of billions from foreign labor super-exploited via offshoring. This is the transnational dynamic. This is why globalist push the denationalization agenda (see The Denationalization Project and the End of Capitalism; The Attack on Nationalism).
