One small point: Undocumented immigrants absolutely do pay taxes. They pay sales taxes, gas taxes, and contribute billions annually in income taxes. It may be true that not all of them pay income taxes, but many of them do.
And not for nothin, but there are plenty of citizens who pay little or no taxes too. And if you’re worried about people not paying their fair share of taxes, it’s weird to focus on such an underprivileged group when our corporations and billionaires are almost the whole fuckin pie chart. It’s not even close.
