My commentary: I appreciate die-hard racists will say "It doesn't matter if they use less welfare, they shouldn't be here in the first place." Thinking this argument must be economically sound, as zero immigrants can only mean zero cost associated with immigrants, and nothing's cheaper than that.

Cato addresses that as well. In "Immigrants' Recent Effects on Government Budgets: 1994"2023"

For each year from 1994 to 2023, the US immigrant population generated more in taxes than they received in benefits from all levels of government.

Over that period, immigrants created a cumulative fiscal surplus of $14.5 trillion in real 2024 US dollars, including $3.9 trillion in savings on interest on the debt.

Without immigrants, US government public debt at all levels would be at least 205 percent of gross domestic product (GDP)"nearly twice its 2023 level. https://www.cato.org/white-paper/immigrants-recent-effects-government-budgets-1994-2023
