I believe the basic premise of "tired poor wretched masses" still rings true. The backbone of our agricultural and industrial sectors has long been formed on the backs of immigrant labor. And in every case the new immigrant group was disparaged by their more integrated counterparts.
The issue of lazy people being lazy i can not help you with. I have never "not had a job" so i don't know why that is okay for some. I do believe we should extend benefits to those who are genuinely seeking employment as a safety net and I don't think it is fair to punish children for their parents faults when it is unecessary to do so.
As ana side though i often struggle with the issue the "religious right" has with caring for the poor.
"For you always have the poor with you, and whenever you will, you can do good to them; but you will not always have me."
But when you give a feast, invite the poor, the maimed, the lame, the blind, and you will be blessed, because they cannot repay you. You will be repaid at the resurrection of the just."
"And he lifted up his eyes on his disciples, and said: "Blessed are you poor, for yours is the kingdom of God."
"You lack one thing; go, sell what you have, and give to the poor, and you will have treasure in heaven; and come, follow me."
Truly, I say to you, it will be hard for a rich man to enter the kingdom of heaven.
Again I tell you, it is easier for a camel to go through the eye of a needle than for a rich man to enter the kingdom of God."
