"Uneducated, Unskilled, and Largely Unemployable"

From American Thinker: "Want some perspective on why so many blue sanctuary cities have so many homeless encampments hovering around? Try the reality that illegal immigrants are routinely given free public housing by the U.S., based on the fact that they are uneducated, unskilled, and largely unemployable. Those are the criteria, and now importing poverty has never been easier."

Read that phrase again: "uneducated, unskilled, and largely unemployable".  So can the Democrats explain to me how their presence benefits our country?
