"They have arried in the Land of opportunity and the opportunities are swirling dizzily promiscuously around them"

Is this quote suppose to have a negative connotation? The passage I got it from is about someone arriving to America and being disappointed but I cant tell if he is saying this quote before he got to America and expecting opportunities or if he said it after he got there and is disappointed

My interpretation is that there are so many opportunities in America that the immigrant is overwhelmed. I see only positive connotations.
