Because liberals think that “Give us your poor, give us your tired’ means “Give us your ingrates who won’t lift a finger to help themselves, Ever, and we’ll take care of them at taxpayer expense, sop these ingrates can sit around smoking pot and drinking beer all day long while we give them nearly $45,000 a year to live on, while at the same time allowing legal citizen seniors, who worked all their lives, and were a productive group of people beneficial for this country, to only get around $10,000 a year to try to get by on”
As for that silly poem on a plaque at the Statue of Liberty, it is a sentimental expression, not public policy. It also contains the phrase "yearning to be free" not "yearning to swill at the public trough".
